実験手順

Following the procedure for the synthesis of Preparation III, the title compound was prepared from tert-butyl 3-(N-{(1R)-2-[4-(2-aminophenyl)piperazinyl]-1-[(4-chlorophenyl)methyl]-2-oxoethyl}carbamoyl)(3S)-1,2,3,4-tetrahydroisoquinoline-2-carboxylate (Preparation IX) (250 mg, 0.40 mmol) in ClCH2CH2Cl (1.5 mL), pyridine (0.040 mL, 0.44 mmol), and 2-nitro-α-toluenesulfonyl chloride (Aldrich) (104 mg, 0.44 mmol). The crude was treated with a soln of HCl satd EtOAc, which resulted in the precipitation of the salt. This material was collected by filtration, dried in vacuo, and recrystallized from MeOH to afford the product as the HCl salt (18 mg). MS (ESI, pos. ion) m/z: 717 (M+H). Calc'd for C36H37ClN6O4S: 716.
