Hydrochloric Acid → HCID 21088627, compound

Participants

Reaction Steps

A mixture of methyl 3-[4-(4-chlorophenyl)-2-[3,4-(methylenedioxy)phenyl]-5-oxazolyl]propionate (1.29 g), potassium hydroxide (0.44 g), methanol (20 mL) and tetrahydrofuran (15 mL) was stirred at room temperature for 2 hrs. The reaction mixture was poured into dilute hydrochloric acid, and extracted with ethyl acetate. The organic layer was washed with water, dried over anhydrous magnesium sulfate, and concentrated to give 3-[4-(4-chlorophenyl)-2-[3,4-(methylenedioxy)phenyl]-5-oxazolyl]propionic acid (1.22 g, 98%) as a colorless powder. Recrystallization from ethyl acetate-hexane gave colorless prism crystals. melting point: 199–200° C.
