53617-36-0, 3h) (R)-1-(4-methyl-2-oxo-2,3-dihydro-benzoxazol-6-ylmethyl -2-[4-(4-methyl-piperazin-1-yl)-piperidin-1-yl]-2-oxo-ethyl 4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidine-1-carboxylate A solution of 510 mg (1.0 mmol) (R)-1-carboxy-2-(4-methyl-2-oxo-2,3-dihydrobenz-oxazol-6-yl)-ethyl 4-(2-oxo-1,2,4,5,-tetrahydro-1,3-benzodiazepin-3-yl)-piperidine-1-carboxylate, 365 mg (1.12 mmol) TBTU, 230 muL (1.31 mmol) ethyldiisopropylamine in 80 mL THF was stirred for 30 min at RT, then combined with 210 mg (1.12 mmol) 1-methyl-4-piperidin-4-yl-piperazine and stirred for 22 h at RT. To complete the reaction the mixture was again combined with 100 mg (0.3 mmol) TBTU and 50 mg (0.27 mmol) 1-methyl-4-piperidin-4-yl-piperazine and 40 mL THF and stirred for a further 4 h at RT. The reaction solution was diluted with 250 mL EtOAc and extracted twice with 60 mL saturated NaHCO3 solution. The organic phase was dried over Na2SO4, filtered and evaporated down i.vac. The residue was purified by chromatography (Alox, DCM/MeOH 50:1 to 25:1), the fractions containing the product were combined, evaporated down i.vac., combined with diethyl ether, filtered off and dried. Yield: 440 mg (65percent of theory) ESI-MS: (M+H)+=674 Rf=0.46 (Polygram-Alox, DCM/MeOH 25:1)
The synthetic route of 53617-36-0 has been constantly updated, and we look forward to future research findings.
