Reaction Steps

6-Fluoro-1-hydroxy-3-morpholin-4-yl-xanthen-9-one (15 mg, 0.05 mmol) and 2-pyridylmethanol (8 mg, 0.07 mmol) were dissolved in DMSO (0.25 mL) and KHMDS (0.5 M in toluene, 0.24 mL) was added. The reaction mixture was heated to 80° C. for 16 hours. The reaction was quenched with sat. NH4Cl/water (1:1, 2 mL) and the solids were filtered. The crude solid was purified via flash chromatography eluting with CH2Cl2/MeOH (98:2) to produce 4.9 mg (25%). 1H NMR (CDCl3, 400 MHz) δ: 12.80 (s, 1H), 8.63 (d, 1H), 8.13 (d, 1H), 7.76 (dd, 1H), 7.52 (d, 1H), 7.27-7.24 (m, 1H), 7.02 (d, 1H), 6.88 (s, 1H), 6.27 (s, 1H), 6.23 (s, 1H), 5.31 (s, 2H), 3.86-3.83 (m, 4H), 3.37-3.35 (m, 4H). LRMS (APCI, positive): Da/e 405.1 (m+1).
