(4-Bromo-3-methyl-phenyl)-(4-methyl-piperazin-1-yl)-methanone → 1-FORMYL-4-METHYLPIPERAZINE

Participants

Reaction Steps

Using bis-(4-methoxy-benzyl)-[5-(2-morpholin-4-yl-6,7-dihydro-5H-pyrrolo[2,3-d]pyrimidin-4-yl)-pyrimidin-2-yl]-amine (100 mg) and (4-bromo-3-methyl-phenyl)-(4-methyl-piperazin-1-yl)-methanone (167 mg) instead of 4-chloropicolinic acid t-butylamide, in the same manner as Example 1-D-07, a crude product of 4-(4-{2-[bis-(4-methoxy-benzyl)-amino]-pyrimidin-5-yl}-2-morpholin-4-yl-5,6-dihydro-pyrrolo[2,3-d]pyrimidin-7-yl)-3-methyl-phenyl]-(4-methyl-piperazin-1-yl)-methanone was obtained, and then the PMB groups were removed according to the above Deprotection method 3, to obtain the desired compound (D-142) as a pale yellow powder (25 mg, 26%).
