Reaction Steps
A mixture of 0.10 g (0.17 mmol) 2-(3,5-bis-trifluoromethyl-phenyl)-N-[4-(4-fluoro-2-methyl-phenyl)-6-(2-hydroxy-1-hydroxymethyl-ethylamino)-pyridin-3-yl]-N-methyl-isobutyramide (Example 142), 12 mg (0.39 mmol) paraformaldehyde and 61 mg (0.51 mmol) magnesium sulfate in 2 ml 1,2-dichloromethane was heated at 85° C. until complete consumption of starting material. After cooling to room temperature the reaction mixture was diluted with water and extracted with 3 portions of tert-butyl methyl ether. The combined organic extracts were dried over sodium sulfate and concentrated in vacuo. Flash column chromatography gave 60 mg (59%) of the title compound as an off-white solid.
