Reaction Steps
A solution of phloroglucinol (0.47 g) and ethyl 2-(1-naphtylmethyl)-acetoacetate (1.00 g) in ethanol (20 ml) was treated with dry HCl at 0° C. for 3 hours and the solution kept at that temperature overnight. Solvent was evaporated and the precipitate triturated with water and recrystallized from isopropanol-water (1:1). Yield 0,96 g (78%). Melting point 275-280° C.
