実験手順

A reaction mixture of 1-(3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl)guanidine (0.300 g, 0.81 mmol) and potassium carbonate (0.337 g, 2.44 mmol) in ethanol (5 mL) was stirred at 50° C. for 5 minutes. 3-(2-methoxy-2-phenylacetyl)dihydro-2H-pyran-4(3H)-one (0.161 g, 0.65 mmol) in ethanol (0.5 mL) was added dropwise to the reaction mixture and the resulting mixture was stirred at 50° C. overnight. The solvent was evaporated and the residue was partitioned between water and dichloromethane. The water phase was extracted twice with dichloromethane. The combined organic layer was dried over MgSO4, filtered, concentrated and purified by preparative HPLC yielding 4-(methoxy(phenyl)methyl)-N-(3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl)-7,8-dihydro-5H-pyrano[4,3-d]pyrimidin-2-amine (8.00 mg, 2%).
