(4-Fluorophenoxy)acetyl chloride → 1-[2-(4-Fluorophenoxy)ethyl]-4-(9-fluoro-3-propan-2-yl-5,6-dihydrobenzo[b][1]benzothiepin-5-yl)piperazine

Participants

Reaction Steps

A solution of 2.6 g of 3-fluoro-8-isopropyl-10-piperazino-10,11-dihydrodibenzo(b,f)thiepin in 15 ml of chloroform was stirred and treated dropwise with 1.7 g of 4-fluorophenoxyacetyl chloride and the mixture allowed to stand for 12 hours. It was then diluted with chloroform, washed with a 5% sodium hydroxide solution and water, dried with potassium carbonate, filtered and evaporated. The oily residue (3.7 g, 100%) was the crude 3-fluoro-10-[4-(4-fluorophenoxyacetyl)-piperazino]-8-isopropyl-10,11-dihydrodibenzo(b,f)thiepin which was used in this state for further work.
