Methane → HCID 66733858, compound

Participants

Reaction Steps

A mixture of 3-(3,5-difluoro-4-methyl-phenyl)-acrylic acid butyl ester (7.651 g; 30.089 mmol) and 10% palladium over activated charcoal (0.760 g) was placed under nitrogen before MeOH (100 ml) was carefully added. The resulting suspension was placed under vacuum, then under hydrogen (1 atm), and the reaction mixture was vigorously stirred at rt for 2 h45. The reaction mixture was filtered over a pad of celite, and concentrated under reduced pressure to give the expected product 3-(3,5-difluoro-4-methyl-phenyl)-propionic acid butyl ester as a yellow oil which was further dried under HV (6.960 g; 90%). LC-MS: tR=1.10 min; [M+H]+: no ionisation.
