Pivaloyl chloride → N-[1-(2,2-dimethylpropanoyl)azetidin-3-yl]-2-(3-fluorophenyl)pyrimidine-5-carboxamide

Participants

Reaction Steps

To a solution of N-azetidin-3-yl-2-(3-fluorophenyl)pyrimidine-5-carboxamide (50 mg, 0.16 mmol) in DMF (1.0 mL) was added DIPEA (0.06 mL, 0.32 mmol) and pivaloyl chloride (30 mg, 0.24 mmol). The mixtures were stirred at room temperature overnight. The mixture was partitioned between ethyl acetate and brine. The organic layer was dried (MgSO4), filtered and concentrated to give a solid, which was purified by chromatography (silica, 80% EtOAc/Hex) to give the product, N-[1-(2,2-dimethylpropanoyl)azetidin-3-yl]-2-(3-fluorophenyl)pyrimidine-5-carboxamide (50 mg, 86%). HRMS (M+H)=357.1727 expected, observed=357.1799.
