Reaction Steps
The ester from Example 54 (1.4 g) was dissolved in 25 ml of absolute alcohol and hydrogenated at atmospheric pressure in the presence of 0.2 g of 10% palladium on charcoal. The catalyst was removed by filtration on diatomaceous earth and after removal of the solvent, 0.9 g of racemic-3,4-dihydro-7-hydroxy-2H-1-benzopyran-3-carboxylic acid ethyl ester was obtained as a white solid.
