Procedure

The crude 5-hydroxy-5-diethylaminopropyl-9-methyl-6,7,8,9-tetrahydro-5H-benzocycloheptene is dissolved in 100 ml. of diethyl ether and added to 500 ml. of liquid ammonia. The solution is treated with 20 g. of lithium in small portions. After one-half hr., the mixture is treated slowly dropwise with absolute ethanol until the color discharges completely. After removal of NH3, the residue is cooled, treated with water and extracted with ether. The dried extracts are freed of solvent leaving crude 5-diethylaminopropyl-9-methyl-1,4,6,7,8,9-hexahydro-5H-benzocycloheptene, which is converted to the corresponding tetrol as described hereinbefore.
