Procedure: To a stirred solution of 1-(3-phenylpropionyl)piperazine (115 g) in toluene (557 ml) and triethylamine (76 ml) was added benzoyloxyacetyl chloride (87 ml) at such a rate to keep the temperature below 30° C. After 30 min water (577 ml) was added and the reaction was stirred for a further 30 min. The layers were separated and the organic layer was washed with sodium carbonate and sodium chloride solution. The dried solution was evaporated in vacuo to give 193 g of 1-[(phenylmethoxy)acetyl]-4-(3-phenylpropionyl)piperazine. the temperature below 30° C The layers were separated the organic layer was washed with sodium carbonate and sodium chloride solution The dried solution was evaporated in vacuo
