Procedure

A well stirred mixture of 111.8 g of piperidine, 103 g of pyridine and one liter of anhydrous ether was treated dropwise with 220 g of freshly distilled 4-fluorophenyl acetyl chloride. This mixture was stirred overnight, then filtered and the filtrate washed successively with water twice, 0.1N sodium hydroxide twice, 0.1N hydrochloric acid twice, water and saturated sodium chloride, then dried in vacuo. The residue was distilled giving a yellow liquid which crystallized on standing, giving 245 g of N-(4-fluorophenylacetyl)piperidine.
