Procedure

To a solution of (3S,6R)-1-[6-(4-acetyl-3-fluorophenyl)-2-amino-4-pyrimidinyl]-6-methyl-3-piperidinecarboxylic acid (308 mg, 0.827 mmol) and HATU (377 mg, 0.992 mmol) in DMF (3 mL) was added Hunig's base (0.289 ml, 1.654 mmol), and the mixture was stirred at room temperature for 15 minutes. Then benzylamine (0.11 mL, 0.99 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 onto water, and EtOAc was added to extract the product. The product stayed in the EtOAc layer. The organic solution was concentrated to dryness to give the title compound (339 mg) as a yellow solid. LC-MS (ES) m/z=462 [M+H]+.
