Reaction Steps
A solution of tert-butyl 4-(5-chloro-2-fluorobenzoyl)piperidine-1-carboxylate (287.9 mg, 0.843 mmol) in dioxane (2.41 mL) was treated with HCl (2.11 mL, 8.43 mmol) at rt and the resulting reaction mixture was stirred overnight. The reaction mixture was diluted with hexanes and filtered by suction to afford (5-chloro-2-fluorophenyl)(piperidin-4-yl)methanone as its HCl salt (146 mg, 62.3%) as a yellow solid. ESI-MS m/z [M+H]+242.20.
