실험 절차

A mixture of 3-methoxyaniline (61.6 g), methyl chloroacetate (44 ml), sodium acetate trihydrate (114 g) and methanol (70 ml) was heated under reflux for 18 h. The mixture was poured into water (500 ml) and extracted with dichloromethane (3×250 ml). The combined, dried organic extracts were evaporated and the residue was treated with 10% concentrated sulphuric acid in methanol (250 ml). After 3 h the solution was poured carefully into 8% sodium bicarbonate (1200 ml) and partitioned with ether (4×500 ml). The combined organic extracts were washed successively with 0.5M citric acid solution (5×200 ml) and brine (500 ml), dried and evaporated to give an oil. Purification by FCC eluting initially with ether:petroleum ether 60°-80° (2:3) and then with ether:petroleum ether 60°-80° (1:1) gave the title compound (52 g) as an oil, t.l.c. (System A, 1:1) Rf 0.31.
