Reaction Steps

To a solution of phthalide (2.0 g, 14.9 mmol) in THF (60.0 ml) at −78° C. was added 1.0M LiHMDS/THF (15.7 ml) over 10 minutes. The reaction was stirred for 15 minutes at −78° C. and then the ice bath was removed. The reaction was quenched into dry ice using a cannula and then allowed to warm to room temperature. After adding 40 ml hexane, the cloudy mixture was rotary evaporated and chased with hexane to give lithium 3-oxo-1,3-dihydro-2-benzofuran-1-carboxylate as a yellow solid (2.86 g, 100%).
