実験手順: 0.05 mol (8.35 g) of 3,4methylenedioxynitrobenzene is introduced into 42 ml of N-acetylethanolamine. The mixture is heated to the region of 100° C., with stirring, and 0.055 mol (3.7 ml) of 15N potassium hydroxide solution is then added.

After 1 hour, the reaction mixture was heated to 40°-50° C. and then, after a further 0.5 hour, cooled to ice-bath temperature. Next, benzyl bromide (13.8 ml, 116 mmol) was added and the resulting suspension stirred at room temperature for 18 hours, before being cautiously quenched with water (400 ml). The resulting mixture was extracted with ethyl acetate (2×300 ml) and the combined extracts washed with water (200 ml), dried (Na2SO4) and evaporated under reduced pressure. The resulting residue was partitioned between ethyl acetate and water, then the organic phase washed thrice with water, dried (Na2SO4) and evaporated under reduced pressure. The crude product was purified by column chromatography on silica gel, eluting with a solvent gradient of methanol:ethyl acetate (0:100 to 10:90), to give the required product (7.8 g) as an oil.

The reaction mixture is heated at 80° C. in a sealed tube for 1.5 hours, cooled to room temperature, and then quenched by the addition of water (15 ml). Ice is added to the reaction mixture and, while stirring, a yellow precipitate is formed. This solid is collected by filtration and placed in the vacuum oven to dry (60° C. for 16 hours). This affords the title compound as a yellow solid (0.199 g, 52%). Mass (m/z): 383.2 (M++1), 381.1 (M+−1). cooled to room temperature quenched by the addition of water (15 ml) Ice is added to the reaction mixture while stirring a yellow precipitate is formed This solid is collected by filtration to dry (60° C. for 16 hours)
