To a stirred solution of 4-(bromomethyl)-2-methoxy-1-nitrobenzene (Preparation 104, 0.2 g, 0.813 mmol) in dry THF (5 ml), was added triethylamine (0.1 g, 1 mmol) followed by a solution of dimethylamine in THF (0.5 ml of a 2M solution, 1 mmol). After stirring for 1 hour at room temperature, the solvent was removed in vacuum and the crude product was purified by silica gel column chromatography eluting with 10% methanol in ethyl acetate to afford the title compound as a white powder (0.16 g, 94%).
