PROCEDURE

实验过程

Fluoren-9-ylmethyl (3R)-3-(N-{(1R)-2-[4-(2-aminophenyl)piperazinyl]-1-[(4-chlorophenyl)methyl]-2-oxoethyl}carbamoyl)-1,2,3,4-tetrahydroisoquinoline-2-carboxylate was prepared according to the procedure for Preparation II using fluoren-9-ylmethyl (3R)-3-(N-{(1R)-1-[(4-chlorophenyl)methyl]-2-[4-(2-nitrophenyl)-piperazinyl]-2-oxoethyl}carbamoyl)-1,2,3,4-tetrahydroisoquinoline-2-carboxylate (1.4 g, 1.8 mmol) and SnCl2.2H2O (1.7 g, 7.3 mmol) (Aldrich). The crude product was purified by flash chromatography (SiO2, 1:1 EtOAc:hexane) and concentrated in vacuo to afford the desired compound (770 mg). MS (ESI, pos. ion) m/z: 740 (M+H), (ESI, neg. ion) m/z: 738 (M−H). Calc'd for C44H42ClN5O4: 739.29.
