Reaction Steps

(R)-8-Chloro-1-methyl-2,3,4,5-tetrahydro-1H-3-benzazepine glucuronate salt was prepared by addition of a molar equivalent of D-glucuronic acid to a solution of (R)-8-chloro-1-methyl-2,3,4,5-tetrahydro-1H-3-benzazepine in isopropanol, acetonitrile, ethyl acetate, or acetone at 60° C. D-glucuronic acid, dissolved in the corresponding solvent at 60° C., was added dropwise with vigorous stirring. Precipitation occurred immediately and the suspension was allowed to cool and stir overnight. The resulting solid was recovered by filtration and dried in a fume hood overnight. (R)-8-Chloro-1-methyl-2,3,4,5-tetrahydro-1H-3-benzazepine glucuronate salt had an extrapolated melting onset temperature by DSC of about 164° C.
