Procedure
22.0 G. of 4-[10,11-dihydro-2,8-dimethyl-dibenz[b,f]oxepin-10-yl]-1-piperazinecarboxylic acid ethyl ester and 22 g. of potassium hydroxide are stirred in 320 ml. of ethyleneglycol and 1.5 ml. of water for 90 minutes at 160° C. After cooling, the mixture is diluted with 1.3 liters of water and extracted three times with ether. The ethereal extracts are washed twice with saturated sodium chloride solution, dried over sodium sulfate, evaporated in vacuo, and there is obtained crude 1-[10,11-dihydro-2,8-dimethyl-dibenz[b,f]oxepin-10-yl]-piperazine as an oil.
