Reaction Conditions

Reaction Steps

NaOH (309.7 mg, 7.7 mmol) was added to 3-[(2-phenyl-5-trifluoromethyloxazole-4-carbonyl)amino]propionic acid methyl ester (265 mg, 0.77 mmol) dissolved in THF/MeOH/water (25 mL, 4:2:1). The reaction mixture was stirred at 25° C. for 12 hours and concentrated under vacuum. The residue was acidified with 1M HCl up to pH 2 and extracted with ethyl acetate. The extract was washed with brine and dried with anhydrous sodium sulfate and concentrated under vacuum to obtain the desired compound (250 mg, 98%) as a white solid.
