2-Methyl-2-pyrrolidin-1-ylpropan-1-ol (0.3776 g, 2.0682 mmol) was taken up in anhydrous DMF (5 mL). Sodium hydride (0.083 g of a 60% dispersion, 2.0682 mmol) was added. The reaction was stirred at RT until gas evolution was complete. 1-Chloro-2-methoxy-4-nitrobenzene (0.3578 g, 2.0682 mmol) was added. The reaction was heated to 80° C. and stirred for 72 h. Cooled to RT and diluted with EtOAc, (50 mL) and washed with water (3×50 mL). Organics were dried over MgSO4, filtered and concentrated. Crude product was purified by chromatatron (100% CH2Cl2 to 95:5 CH2Cl2:MeOH) to give 0.075 g (0.2551 mmol, 12%) of the product. 1H NMR (CDCl3) δ 7.81 (d, 1H, J=8.8 Hz), 7.73 (s, 1H), 7.15 (d, 1H, J=8.8 Hz), 3.88 (s, 3H), 2.76 (s, 2H), 2.68 (bs, 4H), 1.75 (bs, 4H), 1.38 (s, 6H).
