Reaction Steps

To a solution of 10.0 grams of 8-methoxy-10-[4-(3-hydroxypropyl)piperazino]dibenzo[b,f]thiepin in 50 milliliters of benzene was added 9.1 grams of caprylyl chloride (octanoyl chloride) and the mixture was allowed to stand for 48 hours. Thereafter 150 milliliters of water and 20 milliliters of concentrated aqueous ammonium hydroxide solution was added thereto and the resulting mixture was shaken with benzene. The benzene extract was separated form the aqueous solution, filtered, and the filtrate was washed with water, dried over anhydrous potassium carbonate, and the benzene was evaporated therefrom. The residue was dissolved in 30 milliliters of acetone and to this solution was added a solution of 2.9 grams of maleic acid in 10 milliliters of acetone.
