The free base, 3-[4-(3,4-dimethoxyphenyl)-4-isopropyl-4-cyanobutyl]-6,7-dimethoxy-N-methyl-1,2,3,4-tetrahydroisoquinoline (1, 15 g, 0.032 mol) was dissolved in isopropanol (70 mL) at 70° C., and 6M HCl in isopropanol (5.6 mL) slowly added. After cooling to room temperature, ether (40 mL) was added until the solution became cloudy (saturated), and the resulting mixture stirred overnight. The resulting solid was collected, washed thoroughly with ether-isopropanol (1:1, 50 mL), and dried in vacuo at 50° C. to yield 3-[4-(3,4-dimethoxyphenyl)-4-isopropyl-4-cyanobutyl]-6,7-dimethoxy-N-methyl-1,2,3,4-tetrahydroisoquinoline·HCl (1·HCl, 13.7 g, m.p. 115°-120° C.) as a white powder.
