Participants

Reaction Steps

Using {5-[7-(6-chloro-pyridin-3-yl)-2-morpholin-4-yl-6,7-dihydro-5H-pyrrolo[2,3-d]pyrimidin-4-yl]-pyrimidin-2-yl}-bis-(4-methoxy-benzyl)-amine (200 mg, 0.307 mmol) obtained in Step A in Example 1-D-48 and N-acetylpiperazine (59 mg, 0.461 mmol) instead of N,N,N′-trimethyl ethylenediamine, in the same manner as Example 1-D-48, amination was carried out, to obtain a crude product of 1-{4-[5-(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]-piperazin-1-yl}-ethanone as a yellow solid (120 mg), and then the PMB groups were removed according to the above Deprotection method 2, to obtain the desired compound (D-109) as a yellow powder (46 mg, 57%).
