Reaction Steps
A solution of 2.8 g of methylvinylketone in 5 cc of ethanol is added dropwise within 2 minutes to a solution of 7.8 g of 4-(6,11-dihydrodibenzo[b,e]thiepin-11-ylidene)piperidine [M.P. of the fumarate 245°-247°, produced in a manner analogous to that described in Example 9(a), from 4-(6,11-dihydrodibenzo[b,e]thiepin-11-ylidene)-1-methylpiperidine] in 25 cc of ethanol. The reaction mixture is heated at reflux for 1 hour, is then completely concentrated at reduced pressure, and the oily residue, the title compound, is converted into the hydrogen fumarate form. M.P. 180°-182° (decomp.) from ethanol.
