Procedure

A mixture of 10.0 g. of 10,11-dihydro-spiro[dibenzo[a,d] cycloheptene-5,2'-oxirane] and 100 ml. of anhydrous hydrazine is refluxed for 3 hours, the resulting mixture evaporated in vacuo to dryness, the residue dissolved in methanol and again evaporated in vacuo to dryness. The residue is crystallized from diethyl ether to obtain 5-hydrazinomethyl-10,11-dihydro-5H-dibenzo[a,d]cyclo-hepten-5-ol, m.p. 95°-105° C. (decomp.). It was observed that this product decomposed slowly at room temperature to form dibenzo[a,d]cyclohepten-5-one and thus must be stored at reduced temperatures if to be preserved in relatively pure form for any substantial period of time.
