Reaction Steps

Using 3-bromo-4-fluorobenzoic acid (200 mg, 0.913 mmol) and N-ethylpiperazine (232 μl, 1.10 mmol) instead of morpholine, amidation was carried out in the same manner as Example 1-D-16, to obtain a crude product (292 mg) of (3-bromo-4-fluoro-phenyl)-(4-ethyl-piperazin-1-yl)-methanone. Using a crude product (81.8 mg) of the obtained (3-bromo-4-fluoro-phenyl)-(4-ethyl-piperazin-1-yl)-methanone instead of (3-bromo-4-fluoro-phenyl)-morpholin-4-yl-methanone, and bis-(4-methoxy-benzyl)-[5-(2-morpholin-4-yl-6,7-dihydro-5H-pyrrolo[2,3-d]pyrimidin-4-yl)-pyrimidin-2-yl]-amine (70.0 mg, 0.130 mmol), amination was carried out in the same manner as Example 1-D-16, to obtain a crude product of {3-[4-{2-[bis-(4-methoxy-benzyl)-amino]-pyrimidin-5-yl}-2-morpholin-4-yl-5,6-dihydro-pyrrolo[2,3-d]pyrimidin-7-yl]-4-fluoro-phenyl}-(4-ethyl-piperazin-1-yl)-methanone as a yellow solid (152 mg), and then the PMB groups were removed according to the above Deprotection method 3, to obtain the desired compound (D-203) as a yellow powder (48.5 mg, 70%).
