Procedure
To a solution of (2S,4S)-2-(3-chloro-2-fluoro-benzylcarbamoyl)-4-fluoro-4-{[methyl-(2,2,2-trichloro-ethoxycarbonyl)-amino]-methyl}-pyrrolidine-1-carboxylic acid tert-butyl ester (110 mg, 0.20 mmol) in methanol (5 mL), 1M sodium hydroxide 0.40 mL, 0.40 mmol) was added. The solution was stirred for 2 h at RT then was diluted with water, the methanol was removed under reduced pressure. The aqueous layer was washed with Et2O (2×25 mL). The aqueous layer was acidified until pH 3 with 2N HCl and extracted with EtOAc (2×25 mL), dried with Na2SO4, filtered and concentrated. To the residue (80 mg, 0.17 mmol), (3-chloro-2-fluorophenyl)methanamine (33.9 mg, 0.21 mmol) and HBTU (101 mg, 0.26 mmol) dissolved in DMF (5 mL) was added DIPEA (0.06 mL, 0.35 mmol). The reaction mixture was stirred for 16 h at RT. The reaction mixture was quenched with water, extracted with EtOAc, washed with brine, dried over Na2SO4, filtered and concentrated. Purification by flash column chromatography on silica gel (c-hexane/EtOAc 1:1). MS (UPLC/MS): 592/594 [M+H]+, 636/638 [M+HCOO]−; tR (HPLC conditions f): 2.49 min.
