Reaction Conditions

Reaction Steps

A mixture of 2-methoxy-4-nitro-phenol Compound 36a (0.92 g, 5.4 mmol), potassium carbonate (1.5 g, 10.8 mmol) and 4-(2-chloro-ethyl)-morpholine hydrochloride Compound 56a (1.04 g, 5.65 mmol) in DMF (10 mL) was heated under microwave conditions to 140° C. for 30 minutes. The reaction mixture was filtered, diluted with EtOAc and subsequently washed with water, then brine. The organic layer was dried over sodium sulfate and concentrated to yield 4-[2-(2-methoxy-4-nitro-phenoxy)-ethyl]-morpholine Compound 56b (1.46 g). 1H NMR (400 MHz, CDCl3) δ 7.90 (dd, 1H); 7.77 (d, 1H); 6.93 (d, 1H); 4.26 (t, 2H); 3.97 (s, 3H); 3.79-3.69 (m, 4H); 2.91 (t, 2H); 2.66-2.55 (m, 4H). MS 283 (MH+).
