Reaction Steps
3-Chloro-4-(2,4-difluorobenzyloxy)-6-methyl-1-(1H-indol-5-ylmethyl)-1H-pyridin-2-one (, from Step 2) (1-7 g, 4.1 mmol) was stirred in 26 mL of acetic acid and NaCNBH3 (0.27 g, 4.3 mmol) was added portionwise. The reaction was stirred for 1 hour. The reaction was diluted water, and washed 5 times with ethyl acetate. The combined organics were washed 1 time with brine, dried (MgSO4), filtered, and concentrated under reduced pressure. Purification by flash column chromatography (silica, 100% EtOAc) gave a white solid (1.2 g, 71%): 1H NMR (300 MHz, DMSO-d6) δ 7.64 (app q, J=8.5 Hz, 1H), 7.34 (dt, J=9.5, 2.6 Hz, 1H), 7.17 (app t, J=8.5, 1H), 6.82 (s, 1H), 6.72 (d, J=8.0 Hz, 1H), 6.53 (s, 1H), 6.42 (d, J=8.0 Hz, 1H), 5.48 (br s, 1H), 5.27 (s, 2H), 5.13 (s, 2H), 3.37 (t, J=8.3 Hz, 2H), 2.82 (t, J=8.3 Hz, 2H), 2.35 (s, 3H).
