Reaction Steps

Using 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)-benzoic acid obtained in Step A in Example 1-D-19 and 1-isopropylpiperazine (30.4 μl, 0.212 mmol) instead of 3-(aminomethyl)pyridine, in the same manner as Step B in Example 1-D-19, amidation was carried out, 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]-phenyl}-(4-isopropyl-piperazin-1-yl)-methanone as a yellow solid (64.4 mg), and then the PMB groups were removed according to the above Deprotection method 3, to obtain the desired compound (D-113) as a colorless powder (38.7 mg, 69%).
