HCID 11974305Ajg-049Yield 93%

Procedure

A hydrogen chloride ether saturated solution was added to a solution of 2.9 g (7.0 mmols) of (R)-(+)-5,11-dihydro-5-[1-(4-methoxyphenethyl)-2-pyrrolidinylmethyl]dibenzo[b,e][1,4]oxazepine in 20 ml of dichloromethane, and the mixture was stirred for 5 minutes. Then, the solvent was distilled off under reduced pressure. The resulting residue was recrystallized from a mixed solvent of dichloromethane and diethyl ether to give 2.9 g of (R)-(+)-5,11-dihydro-5-[1-(4-methoxyphenethyl)-2-pyrrolidinylmethyl]-dibenzo[b,e][1,4]oxazepine hydrochloride as a colorless prism crystal in a yield of 93%.
