Reaction Steps

To a solution containing 0.20 g (1.3 mmol) of 3-methyl-5-nitropyridine-2(1H)-one in 5 ml of N,N-dimethylformamide under a nitrogen atmosphere was added 0.037 g (1.6 mmol) of sodium hydride followed by 0.31 g (1.6 mmol) of 1-bromomethyl-2,4-dimethylbenzene. The reaction was allowed to stir at room temperature for 30 min., quenched with water and extracted with ethyl acetate. The organic phase was dried over magnesium sulfate. Filtration, removal of solvent and purification of the residue via biotage eluting with 25% ethyl acetate/hexanes gave 0.12 g (34%) of compound.
