tert-Butyl piperazine-1-carboxylate → HCID 67386241, compound

Participants

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 (70.4 mg, 0.107 mmol) obtained in Step A in Example 1-D-19 and 1-Boc-piperazine (31.7 mg, 0.170 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-[4-{2-[bis-(4-methoxy-benzyl)-amino]-pyrimidin-5-yl}-2-morpholin-4-yl-5,6-dihydro-pyrrolo[2,3-d]pyrimidin-7-yl]-benzoyl}-piperazine-1-carboxylic acid tert-butyl ester as a yellow solid (74.2 mg), and then the PMB groups and BOC group were removed according to the above Deprotection method 3, to obtain the desired compound (D-112) as a colorless powder (41.4 mg, 80%).
