Water (100 mL) was added, and the pH of the mixture was adjusted to around 6 with 2N HCl. The mixture was extracted with EtOAc (3×75 mL). The organic extracts were combined, dried over MgSO4, filtered, evaporated, and dried in vacuo to afford 2-{[(3-chloro-5-methoxypyridin-4-yl)methyl]sulfanyl}-6-(trifluoromethyl)pyrimidin-4-ol (912 mg. 93%); 1H NMR (500 MHz, DMSO-d6): δ 3.97 (s, 3H), 4.59 (s, 2H), 6.68 (s (br), 1H), 8.32 (s, 1H), 8.39 (s, 1H); M+352.
