Reaction Steps
Diethyl 3-methoxy-4-bromophenoxyoxalacetate (D10) (7.8 g, 20 mmoles) was stirred with concentrated sulphuric acid (50 ml) for 30 mins. The mixture was then poured into ice water (500 ml) and extracted with diethyl ether (250 ml). The organics were washed with saturated aqueous sodium bicarbonate, dried (Na2SO4) and evaporated to dryness. Flash chromatography on TLC silica gel eluting with dichloromethane gave the title compound (D11) (3.29 g, 44%)
