Procedure

1-Methyl-6-(4-(2-(piperidin-4-yl)ethoxy)-3-(trifluoromethyl)phenyl)-1H-imidazo[4,5-c]pyridine-4-carbonitrile (0.188 g), 2-(dimethylamino)acetic acid (0.090 g) and DIPEA (0.362 ml) were dissolved in NMP (2.5 ml) and HATU (0.250 g) was then added. The reaction was stirred at room temperature for 16 hours. The reaction mixture was diluted with EtOAc (30 mL) and washed with saturated sodium bicarbonate solution. Organics were dried over sodium sulphate to yield crude. Purification by flash chromatography (10 g SiO2 column, DCM to 5% MeOH in DCM gradient) afforded methyl-6-(4-(3-(methylamino)propoxy)-3-(trifluoromethyl)phenyl)-1H-imidazo[4,5-c]pyridine-4-carbonitrile. (59 mg)
