Reaction Steps
To a mixture of the compound from Step 1 (2.0 g, 11.4 mmol) and aluminum chloride (7.0 g, 52 mmol) in carbon disulfide (20 mL) is added acetyl chloride (1.2 mL, 17.1 mmol). The mixture is heated at 50° C. for 72 h, cooled, quenched with ice water then diluted with ethyl acetate and washed with water and brine, dried over anhydrous sodium sulfate, filtered, concentrated, and chromatographed on silica gel eluting with 40-50% ethyl acetate in heptane to give 2.4 g (97%) of the title compound as a off-white solid. MS (ESI+) m/z 217.1 (M+H). Anal. Calcd for C13H15NO2: C, 71.87; H, 6.96; N, 6.45. Found: C, 71.78; H, 6.98; N, 6.43.
