Embodiment 1
[0085] Example 1: (S)-2-[[[(S)-(1,1'-biphenyl-4-oxyl)]-[((2R,3R,4R,5R)-5-(2 ,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl)-4-fluoro-3-hydroxyl-4-methyltetrahydrofuran-2-yl)methoxy]phosphoryl]amino] Preparation of isopropyl propionate

[0087] Synthesis of Step 1 (S)-2-[[(1,1'-biphenyl-4-oxyl)(pentafluorophenoxy)phosphoryl]amino]propionic acid isopropyl ester
[0088]
[0089] In a 50L glass reactor, under the protection of nitrogen, add phosphorus oxychloride (1.53kg, 10mol) and dichloromethane (10L), stir, and cool down to below -30°C. A dichloromethane (5 L) solution of triethylamine (1.01 kg, 10 mol) was added dropwise, and the internal temperature was kept below -30°C during the dropwise addition. After the dropwise addition was completed, a solution of 4-hydroxybiphenyl (1.7kg, 10mol) in tetrahydrofuran (3.4L) was slowly added dropwise, and stirred for 30min after the dropwise completion. Control the internal temperature below -30°C, add L-alanine isopropyl hydro...

[0098] Example 2: (S)-2-[[[(S)-(1,1'-biphenyl-4-oxyl)]-[((2R,3R,4R,5R)-5-(2 ,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl)-4-fluoro-3-hydroxyl-4-methyltetrahydrofuran-2-yl)methoxy]phosphoryl]amino] Confirmation of the configuration of isopropyl propionate
[0099] Weigh 15 mg of the compound of formula 1a prepared in Example 1 into a 3 mL vial, add 5 mL of dichloromethane / n-heptane mixed solvent system with a volume ratio of 2:1, shake the obtained clear solution, and cover the vial with a parafilm Prick holes on it and place it at room temperature for 6 days to obtain crystals.
[0100] The single crystal sample obtained by the above method is collected by X-ray single crystal diffraction data and its single crystal structure is analyzed. Table 1 lists the single crystal structure data and structure refinement parameters of the n-heptane solvate of the compound of formula 1a. Single crystal structure analysis has determined the absolute configuration of the chiral center in the c...
