Reaction Steps

Bromine (0.15 ml) was added dropwise to a solution of triphenylphosphine (0.8 g) in 15 ml of methylene chloride at 5° C. 5-morpholino-imidazo[1,5-a]quinazoline-3carboxamide (0.5 g) and triethylamine (0.83 ml) were added to the solution. The resulting reaction mixture was stirred at room temperature for 3 hours and evaporated in vacuo. Ethyl acetate (10 ml) was added to the residue and crude crystals of the title compound were isolated by filtration. The dried crystals were dissolved in acetone (30 ml) and an excess of hydrogen chloride in diethyl ether was added separating the hydrochloride of the title compound as beige crystals. M.p. 225°-228° C. Yield 0.3 g.
