Phenylacetyl chloride → HCID 19774552, compound

Participants

Reaction Steps

To a solution of N-(1H-pyrrol-1-yl)-4-pyridinamine (6 g) in 400 ml of dichloromethane containing sodium bicarbonate (6.3 g) was added a solution of phenylacetyl chloride (6.7 g) in 50 ml of dichloromethane. After stirring four hours at ambient temperature, the reaction mixture was evaporated, stirred with water and extracted with ether. The organic extract was washed with water and saturated sodium chloride solution, dried over anhydrous magnesium sulfate, filtered and evaporated to 11 g of an oil. This oil was purified by flash chromatography (silica, 25% ethyl acetate in dichloromethane) to give 10 g of an oil. This oil was converted to the hydrochloride salt in ethanol to give 10.4 g of crystals, d 203°-205°. A 3 g sample was recrystallized from ethanol-ether to give 2.8 g of needles, d 203°-204°.
