tert-Butyl piperazine-1-carboxylate → 4-(2-Amino-pyrimidin-5-yl)-2-morpholin-4-yl-5,6-dihydro-pyrrolo[2,3-d]pyrimidine-7-carboxylic acid methyl-(3-piperazin-1-yl-phenyl)-amide

Participants

Reaction Steps

Using 4-{2-[bis-(4-methoxy-benzyl)-amino]-pyrimidin-5-yl}-2-morpholin-4-yl-5,6-dihydro-pyrrolo[2,3-d]pyrimidine-7-carboxylic acid (3-bromo-phenyl)-methyl-amide (70.5 mg) and N-Boc-piperazine (34.9 mg) instead of 2-piperazin-1-yl-ethanol, in the same manner as Step C in Example 1-D-153, 4-{3-[(4-{2-[bis-(4-methoxy-benzyl)-amino]-pyrimidin-5-yl}-2-morpholin-4-yl-5,6-dihydro-pyrrolo[2,3-d]pyrimidine-7-carbonyl)-methyl-amino]-phenyl}-piperazine-1-carboxylic acid tert-butyl ester was obtained as a crude product. Further, PMB group and BOC group were removed according to Deprotection method 3, to obtain the desired compound (D-154) as a yellow solid (37.9 mg, 78%).
