Reaction Steps

In a 20 mL scintillation vial, 3-(2-(5-bromo-3-phenoxypyridin-2-ylamino)thiazol-4-yl)-2-methoxy-2-methylpropanoic acid (0.087 g, 0.187 mmol) was dissolved in CH2Cl2 (5 mL) and DMF (2 mL) and N-methylmorpholine (0.031 mL, 0.281 mmol), followed by addition of 1-hydroxybenzotriazole. The mixture was cooled to 0° C. and EDCI (0.0467 g, 0.244 mmol) was added. The resulting mixture was agitated for 30 minutes and pyrrolidine (0.020 g, 0.28 mmol) was added. The mixture was then agitated overnight, diluted with 50 mL of CH2Cl2 and washed with citric acid solution and sodium bicarbonate solution, dried and evaporated to give crude product which was purified by chromatography on silica gel, eluting with 50-70% ethyl acetate/Hexane, to provide the title compound (0.079 g, 79% yield) as white solid. 1H NMR (DMSO-d6 δ 1.23 (s, 3H), 1.66-1.80 (m, 4H), 3.03-3.63 (m, 9H), 7.01 (m, 1H), 7.16-7.46 (m, 7H), 8.25 (s, 1H).
