Reaction Steps

In a sealed tube 2.00 g (10.3 mmol) 5-bromo-2-chloropyrimidine, 1.15 mL (13.4 mmol) cyclobutylamine and 2.70 mL (15.5 mmol) DIPEA are added to 12 mL ACN. The reaction mixture is stirred at 50° C. over night, then diluted with EtOAc and washed with water (2×). The org. phase is dried with MgSO4, filtered and the solvent is removed in vacuo.
