Procedure
850 Mg. 8-amino-3-cyanodibenzo[b,f]thiepin is refluxed in a mixture of 20 cc. acetic acid and 20 cc. concentrated hydrochloric acid for 48 hours. The suspended solid is filtered, washed with some acetic acid, dried overnight under vacuum at 70° C. to yield 600 mg. pure compound, m.p. 308°-311° C.
Workup
- filtrationThe suspended solid is filtered
- wash
