Reaction Steps
A mixture of 108 (100 mg, 0.43 mmol) and cyanamide (27 mg, 0.65 mmol) was mixed and heated at 85-100 C. with stirring for 15 minutes. The liquid mass was cooled to room temperature, dissolved in hot water (0.7 mL), and acidified with 1-2 drops of conc. HCl. The thick solid which separated was filtered and dried to give crude 113 (160 mg). This was recrystallized from 5% HCl to give the pure hydrochloride salt of 113 (50 mg, 52%): mp 284-287 C.
