[0197] Example 1-1 , (S)-4-(1-(2-((4-fluorophenyl)ethynyl)-5,7-dihydro-4H-thieno[2,3-c]pyran-3-carboxamide ) ethyl) the preparation of benzoic acid (YJ101)
[0198]
[0199] Tetrahydro-4H-pyran-4-one (2.00g, 20.0mmol), ethyl cyanoacetate (2.50g, 22.0mmol) and sulfur (704mg, 22.0mmol) were dissolved in 30.0mL ethanol, and then added to the solution Morpholine (1.74 g, 20.0 mmol) was added to it, and stirred overnight at 50°C. Use TLC to detect the reaction, after the reaction is completed, the reaction solution is extracted with ethyl acetate and water, the upper organic phase is taken and evaporated to dryness, and purified by column chromatography to obtain a light yellow solid, namely 2-amino-5,7-dihydro -4H-Thieno[2,3-c]pyran-3-carboxylic acid ethyl ester (4.38 g, yield 96%). Dissolve ethyl 2-amino-5,7-dihydro-4H-thieno[2,3-c]pyran-3-carboxylate (450 mg, 2.0 mmol) in 1.5M HCl (10.0 mL) at room temperature Stir for 20 min, then lower the temperature to 0 °C under ice...

[0200] Example 1-2 , (S)-4-(1-(2-((4-fluorophenyl)ethynyl)-5,6-dihydro-4H-cyclopentadiene[b]thiophene-3-carboxamide)ethyl Base) Preparation of Benzoic Acid (YJ102)
[0201]
[0202] Using the same reaction route as for the preparation of compound YJ101, replacing tetrahydro-4H-pyran-4-one with cyclopentanone, compound YJ102 was finally obtained (the yield of the last step reaction was 62%). 1 H NMR (500MHz, DMSO) δ8.59(d, J=7.5Hz, 1H), 7.81(d, J=7.6Hz, 2H), 7.52(d, J=7.7Hz, 2H), 7.45-7.43(m ,2H),7.23(t,J=8.4,8.8Hz,2H),5.18–5.13(m,1H),1.80(m,6H),1.45(d,J=6.8Hz,3H).
