Procedure

Placed ethyl 2-(1-methylpiperidin-4-yl)-2-(6-(4-methylthiazol-2-ylamino)-5-phenoxypyridin-3-ylthio)acetate (prepared in Example 235; 0.405 g, 0.812 mmol) in THF (8 mL) and cooled to 0° C. added LiAlH4 (2.44 mL, 2.44 mmol) and warmed to ambient temperature for 30 minutes. Saturated NH4Cl was slowly added and extracted with CH2Cl2. The organic layer was dried, filtered, and concentrated to give the title compound (0.315 g, 84.9% yield). 1H NMR (d6-DMSO) δ 10.92 (bs, 1H), 8.16 (d, 1H), 7.41 (t, 2H), 7.33 (d, 1H), 7.17 (t, 1H), 7.05 (d, 2H), 6.60 (s, 1H), 4.82 (t, 1H), 3.49 (m, 2H), 2.87 (m, 1H), 2.80 (m, 2H), 2.23 (s, 3H), 2.15 (s, 3H), 1.86-1.53 (m, 6H), 1.29 (m, 1H).
