Participants

Reaction Steps

500 mg of 3,8-dichloro-1-methyl-6-phenyl-1,2,3,4-tetrahydro-1,5-benzodiazocine hydrochloride were heated in a solution of 110 mg sodium in 70 ml methanol under reflux for 12 hours. After evaporation of the methanol in a vacuum the mass was further processed with water/chloroform and the chloroform solution was evaporated and concentrated in a vacuum. The residue was taken up in isopropanol and reacted with an ether solution of hydrogen chloride. There was obtained 7-chloro-1-methyl-2-methoxymethyl-5-phenyl-2,3-dihydro-1H-1,4-benzodiazepine hydrochloride which product also was identical with the product obtained directly by reaction of N-methyl-N-(2-hydroxy-3-benzoylaminopropyl)-4'-chloroaniline in phosphoroxychloride at 120° C. and subsequent reaction with sodium and methanol as disclosed in Examples 4 and 8 of application Ser. No. 355 986; m.p. 198°-210° C.
