Reaction Steps

Methyl 7-(3-chloropropoxy)-4-oxo-8-propyl-4H-1-benzopyran-2-propanoate (2.0 g, 5.35 mmol) was dissolved in a mixture of 25 ml ethyl acetate and 0.32 ml phosphoric acid and hydrogenated at 5 psi and 25° C. using 2 g of 5% Pd/C as catalyst. The product was dissolved in ethyl acetate, washed with 10% sodium carbonate solution, then washed once with water, dried over magnesium sulfate and filtered. The solvent was removed under vacuum to give the product as a colorless oil (1.5 gm, 90% yield).
