Reaction Steps
Under argon, 50 mg (0.15 mmol) of 8-[(2,6-difluorobenzyl)oxy]-6-ethynyl-2-methylimidazo[1,2-a]pyridine-3-carboxylic acid were dissolved in 0.5 ml of dry dimethylformamide, 20.54 mg (0.18 mmol, 1.2 equivalents) of (R)-(−)-2-aminohexanol, 72 μl of diisopropylethylamine (0.44 mmol, 3 equivalents) and 72 mg of HATU (0.19 mmol, 1.3 equivalents) were added and the mixture was stirred at room temperature overnight. A little water was then added, and the mixture was purified directly by preparative HPLC (Method 8). This gave 37.5 mg of the target compound (58% of theory).
