The solution was treated with triethylamine (1.57 g, 15.51 mmol) and trimethylacetylchloride (1.87 g, 15.51 mmol) and the mixture was stirred at room temperature for 1 hour. Silica gel (9 g) was added and the solvent was removed in vacuo. The residue was chromatographed on silica gel eluting with hexanes/ethyl acetate (5:1) to afford 2,2-dimethyl-N-(5-phenylpyridin-2-yl)propanamide (2.58 g) as a white solid.
