Reaktionsschritte
This amide (900 mg, 3.4 mmol) was dissolved in dimethylformamide (100 ml) and potassium carbonate (516 mg) added, followed by iodomethane (0.6 ml, 3.7 mmol). The solution was stirred for 5 hours, then concentrated in vacuo. The residual oil was partitioned between ethyl acetate (50 ml) and H2O (50 ml), the aqueous layer extracted with ethyl acetate (3×50 ml), the combined organic phases washed with brine (20 ml), dried (MgSO4) and evaporated to yield 3-(2-methoxy-4-nitrophenyl)-1-pyrrolidin-1-yl-propan-1-one as a black oil (900 mg, 3.2 mmol);
