Reaction Steps

A mixture of (S)-methyl 2-ethoxy-3-(4-benzyloxyphenyl)propanoate of the formula (9c) (56 g) in aqueous methanol (300 ml) and slurry of 5% palladium carbon (6 g in 60 ml water) was taken in hydrogenation flask and hydrogenated on Parr shake flask at 60 psi pressure for 6-8 h at room temperature. Completion of the reaction was monitored by TLC. After completion of the reaction, the catalyst was filtered and the filtrate was evaporated to yield tile compound of the formula (1) (39 g, 96%).
