Ethyl propiolate (4, 442 mg, 0.46 ml, 4.5 mmol) and ZnCl2 (405 mg, 3 mmol) was added to a solution of naphthalene-1,3-diol (1f, 722 mg, 4.5 mmol) in dry dioxan (15 ml) and the mixture was refluxed under sti
    • 2 (405 mg, 3 mmol) was added to a solution of naphthalene-1,3-diol (1f) (722 mg, 4.5 mmol) in dry dioxan (15 ml) and the mixture was refluxed under stirring for 4 days. After cooling the mixture was poured in 5% HCl (15 ml), condensed to the half of the volume and left overnight in the refrigerator. The precipitated solid was recrystallised from ethyl acetate to give compound 3f (83% yield).
