Procedure

Initially 10-iodo-11-nitro-5H-dibenzo[a,d]cyclohepten-5-one is contacted with pyridine to form 10-nitro-5H-dibenzo[a,d]cyclohepten-5-one. This compound is reduced to 10,11-dihydro-10-hydroximino-5H-dibenzo[a,d]cyclohepten-5-one employing a solution of stannous chloride in concentrated hydrochloric acid and tetrahydrofuran generally at 0°-50° C. for 2-16 hours.
