1-(4-Pyridyl)piperazine → {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-fluoro-phenyl}-(4-pyridin-4-yl-piperazin-1-yl)-methanone

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)-3-fluoro-benzoic acid (80.0 mg, 0.118 mmol) obtained in Step A in Example 1-D-21 and 1-(4-pyridyl)piperazine (38.5 mg, 0.236 mmol) instead of 1-pyridine-3-yl-piperazine, amidation was carried out in the same manner as Step B in Example 1-D-21, 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]-3-fluoro-phenyl}-(4-pyridin-4-yl-piperazin-1-yl)-methanone as a yellow solid (142 mg), and then the PMB groups were removed according to the above Deprotection method 3, to obtain the desired compound (D-286) as a yellow powder (51.2 mg, 74%).
