実験手順

The crude 7-nitro-chroman-2-one (1.1 g, approx. 4.2 mmol) was dissolved in tetrahydrofuran (15 ml). Pyrrolidine (0.35 ml) was added and the reaction mixture stirred for 1 hour. The solution was adsorbed onto silica and eluted using methanol in dichloromethane. 3-(2-hydroxy-4-nitrophenyl)-1-pyrrolidin-1-yl-propan-1-one was obtained as a brown solid (900 mg, 3.40 mmol);
