Participants

Reaction Steps

12.5 g. of 1-methyl-10,11-dihydro-5-(3-methylcarbethoxyaminopropyl)-5-hydroxy-5H-dibenzo[a,d]cycloheptene, 14 g. of potassium hydroxide and 120 ml. of n-butanol are boiled at reflux for 17 hours under nitrogen and with strong stirring. The butanol is removed by distillation under reduced pressure. The residue is taken up in ether and washed with water. 1-Methyl-10,11-dihydro-5-(3-methylaminopropyl)-5-hydroxy-5H-dibenzo[a,d] cycloheptene is obtained as a thick oil by evaporation of the ether.
