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 (4-bromo-phenyl)-methyl-amide (121 mg) obtained in Step B in Example 1-D-160 instead of 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, and N-Boc-piperazine (60 mg) instead of 2-piperazin-1-yl-ethanol, in the same manner as Step C in Example 1-D-153, a crude product of 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 methyl-(4-piperazin-1-yl-phenyl)-amide was obtained. The PMB groups were removed according to Deprotection method 3, to obtain the desired compound (D-161) as a yellow solid (56.1 mg, 67%).
