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 (65.6 mg, 0.0968 mmol) obtained in Step A in Example 1-D-21 and N-ethylpiperazine (24.6 μl, 0.194 mmol) instead of 1-pyridin-3-yl-piperazine, amidation was carried out in the same manner as Step B in Example 1-D-21, and 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-ethyl-piperazin-1-yl)-methanone was obtained as a yellow solid (64.2 mg). Then the PMB groups were removed according to the above Deprotection method 3, to obtain the desired compound (D-138) as a yellow powder (39.2 mg, 76%).
