The solution was cooled to room temperature and filtered free of solid. The solution was washed with ethanol (50 ml) and dried at 65° C. in vacuo for four hours, to give 2.2 g (85%) of a white solid, mp 173°-175° C. Anal. (C23H23N5O4); calc: C=63.73, H=5.35, N=16.16; found: C=63.55, H=5.49, N=16.00.
