To a solution of 2-phenyl-1-p-tolylethanone (5.0 g, 23.78 mmol) in EtOH (475.0 mL) at room temperature was added dropwise tert-butyl nitrite (5.5 mL, 46.2 mmol) followed by sodium ethoxide (4.07 g, 59.8 mmol). The reaction was stirred at room temperature overnight and concentrated under reduced pressure. The residue was dissolved in EtOAc, washed with H2O, brine, dried over MgSO4 and concentrated. The residue was purified by silica gel column chromatography to give the title compound as an orange oil (5.31 g). LCMS m/z=239.9 [M+H]+.
