実験手順

Potassium carbonate (280 mg, 2 mmol) and methyl vinyl sulfone (0.4 ml, 2.1 mmol) were added to a solution of 6-methoxy-7-((piperidin-4-yl)methoxy)-3-((pivaloyloxy)methyl)-3,4-dihydroquinazolin-4-one hydrochloride (0.88 g, 2 mmol) and triethylamine (0.3 ml, 2.1 mmol) in methanol (10 ml) and methylene chloride (10 ml). After stirring for 2 hours at ambient temperature, the volatiles were removed under vacuum. The residue was partitioned between ethyl acetate and water. The organic layer was washed with brine, dried (MgSO4) and evaporated to give 6-methoxy-7-((1-(2-methylsulphonylethyl)piperidin-4-yl)methoxy)-3-((pivaloyloxy)methyl)-3,4-dihydroquinazolin-4-one (0.55 g, 54%).
