PROCEDURE

实验过程

tert-Butyl 3-[N-((1R)-2-{4-[2-({2-[(tert-butoxy)carbonylamino]ethyl}(methylsulfonyl)amino)phenyl]piperazinyl}-1-[(4-chlorophenyl)methyl]-2-oxoethyl)-carbamoyl](3S)-1,2,3,4-tetrahydroisoquinoline-2-carboxylate was prepared according to the procedure for Preparation III using tert-butyl 3-[N-((1R)-2-{4-[2-({2-[(tert-butoxy) carbonylamino]ethyl}amino)phenyl]piperazinyl}-1-[(4-chlorophenyl)methyl]-2-oxoethyl)carbamoyl](3S)-1,2,3,4-tetrahydroisoquinoline-2-carboxylate (Step 1) (370 mg, 0.45 mmol), methanesulfonyl chloride (41 μl, 0.530 mmol), pyridine (40 μl, 0.495 mmol), DMAP (cat.), and ClCH2CH2Cl (15 mL). The crude material was purified by flash chromatography, (SiO2, 1:1 hexane:EtOAc) to afford the desired material (155 mg). MS (ESI, pos. ion) m/z: 839 (M+H), (ESI, neg. ion) m/z: 837 (M−H). Calc'd for C42H55ClN6O8S: 839.44.
