Sodium amide → HCID 18690195, compound

Participants

Reaction Steps

A solution of 22.2 g (137 mmol) of 1-oxo-5-methoxyindane in tetrahydrofuran was added dropwise to a cold suspension of 11 g (274 mmol) of sodium amide in tetrahydrofuran. The resulting mixture was stirred for ten minutes and a solution of 31.3 g (137 mmol) of phenyl-4-methoxybenzoate in tetrahydrofuran was added. Cooling was discontinued and a slight exothermic reaction occurred. The mixture was stirred at ambient temperature for an additional two hours. A thick precipitate developed and the reaction mixture was poured into ice-water. The aqueous mixture was extracted with ethyl acetate. The ethyl acetate extract was evaporated to dryness to obtain 20.7 g of the title compound. mp: 160° C.-162° C.
