実験手順

The title compound was prepared from 2,4-diamino-5-(3-hydroxy-4,5-dimethoxybenzyl)pyrimidine (20.0 g, 72.4 mmol) and allyl bromide by the procedure of Example 1A. Recrystallization from 95% ethanol gave title compound as white crystals (14.9 g); mp 160°-162°. Anal. Calcd for C16H20N4O3 : C, 60.74; H, 6.37; N, 17.71. Found: C, 60.94; H, 6.45; N, 17.62.
