Embodiment 1

[0052] Embodiment 1: the preparation of compound I:

[0053]

[0054] 4,4-bis(4-fluorophenyl)-1-chlorobutane (compound VI-a, 0.56g, 2.0mmol) and L-phenylalanine methyl ester (VII-a, 0.72g, 4.0 mmol) was added to DMSO (10 mL) in a 25 mL single-port reaction vial with magnetic stirring, and stirred at 80° C. for 10 hours. The reactant was transferred to a 250mL separatory funnel, diluted with 150mL ethyl acetate, then washed twice with 50mL of 5% Na2CO3 aqueous solution, washed twice with 60mL of water, and finally washed once with saturated 60mL of NaCl aqueous solution. Then the organic layer was dried over anhydrous sodium sulfate, filtered, concentrated, and purified by column chromatography to obtain compound I (0.97 g, 88%). 1H-NMR (CDCl3, 400MHz): 7.32~7.23(m, 5H), 7.20-7.10(m, 4H), 7.01-6.95(m, 4H), 4.08(t, J=7.7Hz, 1H), 3.64( s,3H), 3.48(m,1H), 2.94(m,2H), 2.63-2.46(m,2H), 2.03-1.96(m,3H), 1.41-1.36(m,2H). 13C-NMR (CD3OD, 100MHz): 178.3, 162.4(d, J=240Hz), 147.9, ...

Embodiment 2

[0055] Embodiment 2: the preparation of compound II:

[0056]

[0057] 4,4-bis(4-fluorophenyl)-1-chlorobutane (compound VI-a, 0.84g, 3.0mmol) and L-leucine methyl ester (VII-b, 0.87g, 6.0mmol ) was added to DMSO (20 mL) in a 50 mL single-port reaction flask with magnetic stirring, and stirred at 80° C. for 16 hours. The reactant was transferred to a 300mL separatory funnel, diluted with 200mL ethyl acetate, then washed twice with 80mL of 5% Na2CO3 aqueous solution, washed twice with 80mL of water, and finally washed once with saturated 80mL of NaCl aqueous solution. Then the organic layer was dried over anhydrous sodium sulfate, filtered, concentrated, and purified by column chromatography to obtain compound II (0.95 g, 81%). 1H-NMR (CDCl3, 400MHz): 7.16-7.12(m, 4H), 6.98-6.92(m, 4H), 3.85(t, J=7.8Hz, 1H), 3.69(s, 3H), 3.22(t, J=6.9Hz,1H),2.56(m,1H),2.24(m,1H),2.03-1.98(m,2H),1.67(m,1H),1.46-1.41(m,5H),0.91(d , J=6.6Hz, 3H), 0.88(d, J=6.6Hz, 3H). 13C-NMR (CD3OD, 100MHz)...

Embodiment 3

[0058] Embodiment 3: the preparation of compound III:

[0059]

[0060] Add 4,4-bis(4-fluorophenyl)-1-chlorobutane (compound VI-a, 0.28g, 1.0mmol) and compound VII-c (0.22g, 2.0mmol) to 15mL with magnetic stirring DMSO (5 mL) in a single-port reaction flask was stirred at 80° C. for 12 hours. The reactant was transferred to a 100mL separatory funnel, diluted with 50mL ethyl acetate, then washed twice with 20mL of 5% Na2CO3 aqueous solution, washed twice with 20mL of water, and finally washed once with saturated 20mL of NaCl aqueous solution. Then the organic layer was dried over anhydrous sodium sulfate, filtered, concentrated, and purified by column chromatography to obtain compound III (0.27 g, 76%). 1H-NMR (CDCl3, 400MHz): 7.76(d, J=7.3Hz, 1H), 7.21-7.11(m, 4H), 7.07-6.98(m, 4H), 6.50(m, 1H), 6.28(d, J=7.2Hz, 1H), 4.11(t, J=7.6Hz, 1H), 3.71(s, 2H), 2.98(d, J=7.3Hz, 2H), 2.61(s, 3H), 2.53-2.48( m,2H), 2.07-1.99(m,2H), 1.48-1.37(m,2H). 13C-NMR (CD3OD, 100MHz): 163.1(d,...
