Reaction Steps

Cesium carbonate (1.07 g, 3.30 mmol) was added to a solution of benzyl 6-(2-chlorophenyl)-2-oxo-1,2-dihydropyridin-3-ylcarbamate (J. Med. Chem. 1994, 37, 3303-3312) (585 mg, 1.65 mmol) and cyclopropylmethyl bromide (0.19 mL, 1.98 mmol) in N,N-dimethylformamide (5 mL). After 4 h, water was added, and the mixture was extracted with ethyl acetate. The organic layer was washed with water (2×), saturated brine, dried over magnesium sulfate, filtered and concentrated. Purification by silica gel chromatography (hexanes→30% ethyl acetate/hexanes) gave the title compound (258 mg). MS 409.0 (M+1).
