Reaction Steps

A mixture of 14.50 g of 4-(2-hydroxy-4-methoxybenzoyl)piperidine, 6.40 ml of benzyl bromide, 10.20 g of sodium bicarbonate and 74.0 ml of dimethylformamide was stirred at 60° for 15 hrs. The reaction mixture was poured into 250 ml of water and a precipitate formed. The precipitate was collected, washed with water and recrystallized from ethanol to yield 10.0 g (57.4%) of product, mp, 123°-125°.
