Cyclopentylamine → (3S,6R)-1-[2-amino-6-(4-cyano-3-fluorophenyl)-4-pyrimidinyl]-N-cyclopentyl-6-methyl-3-piperidinecarboxamide

Participants

Reaction Steps

To a solution of (3S,6R)-1-[2-amino-6-(4-cyano-3-fluorophenyl)-4-pyrimidinyl]-6-methyl-3-piperidinecarboxylic acid (170 mg, 0.478 mmol) and HATU (218 mg, 0.574 mmol) in DMF (3 mL) was added Hunig's base (0.167 mL, 0.957 mmol), and the mixture was stirred at room temperature for 5 minutes. Then, cyclopentylamine (44.8 mg, 0.526 mmol) was added, and the reaction mixture was stirred at room temperature for 0.5 hours. LCMS showed reaction was completed. The reaction was poured into water, and the formed solid was filtered, washed by water and dried to afford the title compound (174 mg) as a yellow solid. LC-MS (ES) m/z=423 [M+H]+.
