참여 물질

반응 단계

A solution of methyl 3-cyano-4-methylbenzoate (compound 1.7, 880 mg, 5.02 mmol, 1.00 equiv) and O,O′-diethyl dithiophosphate (1.41 g, 8.29 mmol, 1.50 equiv) in THF/H2O (40 mL) was stirred at 80° C. (CAUTION: significant gas evolution occurs—this and all other reactions described herein should be carried out in well ventilated fume hoods). After 3 h, the organic solvent was removed under reduced pressure and the residual aqueous phase was extracted with 3×20 mL of ethyl acetate. The combined organic layers were concentrated under reduced pressure to yield 0.85 g (79%) of the title compound as a light yellow solid.
