Reaction Steps

A solution of (6-methoxy-3,4-dihydro-1H-napthalen-2-ylidene)-acetic acid ethyl ester (4.4 g, 18 mmol) in ethyl acetate (35 mL) was hydrogenated over 10% Pd—C (0.9 g) at 50 psi and left overnight. The reaction mixture was filtered through diatomaceous earth and washed with ethyl acetate (200 mL). The filtrate was concentrated to give the title compound (4.0 g, 91% yield) as a clear, colorless oil.
