Reaction Steps

N,N-dibenzyl-4-(2-oxo-3-methylene-1,2,3,5-tetrahydroimidazo[2,1-b]quinazolin-7-yl)oxybutanamide acetate (1.0 g) is dissolved in 50 ml water containing a stoichiometric equivalent of sulfuric acid, and the solution evaporated to dryness. The product is suspended in ethanol and filtered, air dried and recrystallized from methanol/acetone to yield N,N-dibenzyl-4-(2-oxo-1,2,3,5-tetrahydroimidazo[2,1-b]quinazolin-7-yl)oxybutanamide sulfate.
