YieldReaction ConditionsOperation in experiment
With sodium tetrahydroborate; In tetrahydrofuran; at 0℃; for 0.5h;Inert atmosphere; INTERMEDIATE 35 PREPARATION OF 3,3-DIFLUORO-2-METHYLPROP-2-ENOIC ACID Sodium borohydride (250 mg, 6.57 mmol) was added to a solution of 2- (trifluoromethyl)prop-2- enoic acid (460 mg, 3.28 mmol) in THF (10 mL) which had been pre-cooled to 0 C. The reaction mixture was stirred at 0 C for 30 min and quenched with 1M HCl solution. The organic solvent was evaporated under reduced pressure and the aqueous portion was extracted twice with EtOAc. The combined organic portions were dried over Na2SO4, filtered and concentrated under reduced pressure to afford a 3:2 mixture of 3,3,3-trifluoro-2-methylpropanoic acid and the title 3,3-difluoro-2-methylprop-2- enoic acid (270 mg). This mixture was progressed to the next step without further purification. Analytical data for 3,3-difluoro-2-methylprop-2-enoic acid: LC-MS (Method A): m/z = 120.9 [M-H]-, 0.57 min.
