Glycolic Acid → HCID 56929770, compound

Participants

Reaction Steps

(R)-8-Chloro-1-methyl-2,3,4,5-tetrahydro-1H-3-benzazepine glycolate salt was prepared by the addition of one equivalent of glycolic acid to a solution of (R)-8-chloro-1-methyl-2,3,4,5-tetrahydro-1H-3-benzazepine in ethyl acetate or acetone at 60° C. Glycolic acid, at 60° C., was added dropwise, in the corresponding solvent, with vigorous stirring. Precipitation occurred immediately and the suspension was allowed to cool and stir overnight. The resulting solid was recovered by filtration and air-dried in a fume hood overnight. (R)-8-Chloro-1-methyl-2,3,4,5-tetrahydro-1H-3-benzazepine glycolate salt had an extrapolated melting onset temperature by DSC of about 138° C.
