関与物質

反応手順

A solution of (4-chloro-phenyl)-acetic acid (6.29 g, 0.03 mol) in ethanol (38.4 mL) was treated with a catalytic amount of sulfuric acid. The reaction mixture was heated under reflux for 12 h. The reaction was then concentrated in vacuo. Flash chromatography (Merck Silica gel 60, 230-400 mesh, 50/50 hexanes/ethyl acetate) afforded (4-chloro-phenyl)-acetic acid ethyl ester (6.45 g, 88%) as a pale yellow solid: mp 39-41° C.; EI-HRMS m/e calcd for C10H11ClO2 (M+) 198.0448, found 198.0452.
