Reaction Steps

Following the procedure described in Preparation 58, 100 mg of 6-acetoxy-2,5,7,8-tetramethyl-2-(4-nitrophenoxymethyl)-2H-chromene (prepared as described in Preparation 49) were dissolved in 2 ml of methanol and, in the presence of 20 mg of 10% w/w palladium-on-carbon, the compound was reduced under 1 atmosphere (about 1 bar) pressure of hydrogen, to give the title compound melting at 138°-140° C.
