Reaction Steps

2-(4-Hydroxyphenyl)-7-isopropenyl-1,3-benzoxazol-5-ol (64 mg, 0.24 mmol) was dissolved in a mixture of EtOAc (5 mL) and absolute ethanol (5 mL) and placed under an inert atmosphere with argon. To this mixture was added 10% Pd—C (25 mg). The solution was, hydrogenated on a Parr apparatus at 25 psi for 3 h. The solution was filtered through celite and rinsed with ethanol. The filtrate was concentrated and the residue purified by flash chromatography (50% EtOAc/petroleum ether) to give (58 mg, 90% yield) of the product as a tan solid, m.p. 200° C.; MS m/e 270 (M+H)+.
