3,5-Dimethoxyphenylpropionic acid Use and Manufacturing

To a solution of 3-(3, 5-Dimethoxy-phenyl)-acrylic acid (12g, 57.7mmol) in EtOAc (100ml) and MeOH (100ml) was added carefully 10percent Pd/C (1.3g), the reaction mixture was shaken in Parr apparatus for 5hs under 30-40 psi of hydrogen, then the solution was passed through a celite pad, the filtrate was concentrated and dried at 5OTo a flame dried flask under argon was added Pd/C (10percent, 1 g) and ethanol (15 mL) to wet the palladium. A solution of [3- (3, 5-DIMETHOXYPHENYL)-2-PROPENOIC] acid (10 g, 48 [MMOL)] in ethanol was added slowly to the flask containing Pd/C under argon. A hydrogen balloon was connected to the flask and stirred under hydrogen for 16 h. The reaction was filtered through a [CELITE PLUG] and the filtrate was evaporated under vacuum. The residue was purified by Biotage to obtain [3- (3, ] 5- dimethoxyphenyl) propanoic acid (9.89 g, 47 [MMOL)] as a solid in 98percent [YIELD. 1H] NMR (CDCI3) [5] 2.7 (t, 2H), 2.9 (t, 2H), 3.8 (s, 6H), 6.4 (m, 3H); MS (ES) 211.0 (M+H) +.
