反応手順
A solution of resorcinol (4.84 g., 0.041 moles) and ethyl 1-naphthoylacetate (10 g., 0.041 moles) in ethanol (50 ml.) was saturated with hydrogen chloride at room temperature (cooling with ice/water) and left to stand in s stoppered flask for 24 hours. The solution was filtered to give the required coumarin as an orange solid (7.8 g., 66%, m.p. 292°-295° C.
