Cooled to rt and precipitate formed from DCM (10 mL) was filtered off. The solvent of mother liquor was removed under reduced pressure and repeated the precipitation process with Et2O (10 mL). Trituration in methanol (10 mL) afforded the desired product as a yellow solid (30 mg, 4 %). MS (m/z): 397 (MH+). 1H NMR (CDCl3) δ: 9.37 (s, 1H), 8.37 (d, 1H), 8.26 (dd, 1H), 7.70 (m, 1H), 7.49 (m, 1H), 4.46 (q, 2H), 3.61 (s, 3H), 2.60 (s, 3H), 1.43 (t, 3H).
