Reaction Steps

Using 4-chloropicolinic acid chloride and 4-(2-hydroxyethyl)piperazine instead of N-Boc-piperazine, amidation was carried out in the same manner as Step A in Example 1-D-199, to obtain (4-chloro-pyridin-2-yl)-[4-(2-hydroxy-ethyl)-piperazin-1-yl]-methanone. 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 (282 mg, 0.52 mmol), and (4-chloro-pyridin-2-yl)-[4-(2-hydroxy-ethyl)-piperazin-1-yl]-methanone (175 mg, 0.65 mmol) instead of 4-chloropicolinic acid t-butylamide, amination was carried out in the same manner as Example 1-D-07, to obtain 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)-pyridin-2-yl]-[4-(2-hydroxy-ethyl)-piperazin-1-yl]-methanone as a colorless solid (210 mg), and then the PMB groups were removed according to the above Deprotection method 2, to obtain the desired compound (D-202) as a colorless powder (114 mg, 80%).
