実験手順

tert-butyl (2R)-2-{[(3-{[(2,2-dimethylpropanoyl)oxy]methyl}-7-methoxy-4-oxo-3,4-dihydroquinazolin-5-yl)oxy]methyl}pyrrolidine-1-carboxylate (0.750 g, 1.5 mmol) was stirred in a 7N solution of ammonia in methanol (250 ml) at room temperature for 24 hours. The mixture was evaporated under reduced pressure to give tert-butyl (2R)-2-{[(7-methoxy-4-oxo-3,4-dihydroquinazolin-5-yl)oxy]methyl}pyrrolidine-1-carboxylate (0.560 g, 100% yield) which was used in the next stage without further purification.
