Reaction Steps

To a suspension of lithium chloride (0.28 g, 6.6 mmol) in MeCN (9 mL), were added trimethyl phosphonoacetate (available from Aldrich) (0.76 mL, 5.3 mmol), DBU (0.79 mL, 5.3 mmol), and 3-benzyloxyacetophenone (available from Aldrich) (1.00 g, 4.4 mmol). The mixture was stirred overnight at reflux (100° C.), cooled to room temperature, diluted with EtOAc, washed with water and brine, dried (MgSO4), and concentrated. The crude product was chromatographed on silica gel (0-10% EtOAc/hexane) to afford 42.1 (0.45 g, 36%) as a colorless oil.
