Reaction Steps

2-Fluorobenzoyl chloride (10.5 g, 66.5 mmol) was added to a stirred solution of 4-piperidone hydrochloride (6.0 g, 60.5 mmol) and DIPEA (3.0 mL, 17.1 mmol) in DCM (150 mL). The mixture was stirred at room temperature for 2 hours and extracted with a 10% solution of citric acid, a saturated solution of Na2CO3 and H2O. The organic layer was separated, dried (Na2SO4), filtered and the solvent evaporated in vacuo to yield 1-(2-fluorobenzoyl)-4-piperidinone (5.5 g, 41% yield) that was used in the next step without further purification.
