Reaction Steps

2-Chloroethylmorpholine hydrochloride (104 mg, 0.6 mmol) was added to a slurry of the product of Step 2 (135 mg, 0.3 mmol) and powdered K2CO3 (1 g) in DMF (2 mL) and the mixture was heated to 80° C. for 3 h. The mixture was cooled, diluted with H2O and extracted with EtOAc. The combined organic extracts were washed with H2O and brine, dried (MgSO4), filtered and the filtrate was concentrated to give a yellow oil which was purified by reverse phase HPLC to give the title compound (50 mg, 30%). 1H NMR (400 MHz, CD3OD) δ ppm 9.13 (s, 1H), 8.69 (s, 1H), 8.09 (d, J=9.3, 1H); 7.92 (s, 1H), 7.69 (d, J=8.0, 1H), 7.60-7.53 (m, 2H), 7.12 (d, J=8.0, 1H), 6.67 (d, J=9.4, 1H), 4.76 (br q, 2H), 4.53 (br m, 2H), 3.83-3.70 (m, 8H), 3.33 (m, 2H), 1.46 (br t, 3H). MS (ES+) m/e 572 [M+H]+.
