Reaction Steps

A suspension of 32 g of 1-dimethylamino 3-benzamido 4-orthochlorophenyl butane [(XI), code number 57] in 350 ml phosphorous oxychloride were brought to 100° C. for 12 hours. Then the solvent is evaporated, the residue taken up in water, basified with concentrated aqueous NaOH, extracted with methylene chloride, filtered, the filtrate evaporated and the product obtained chromatographed on an alumina column (elution by means of methylene chloride). Then the product obtained is dissolved in ether, hydrochloric ethanol is added and the precipitate formed is filtered.
