Reaction Steps

A solution of 2-bromo-1-(6-methyl-pyridin-2-yl)-2-quinolin-6-yl-ethanone of Step D (60 mg, 0.176 mmol)in dimethylformamide (1 mL) was treated with 2-aminopyridine (50 mg, 0.53 mmol, 3 equiv), and heated to 80° C. over 4.5 hours. After cooling down, the mixture was treated with water and extracted with ethyl acetate. The organics were concentrated in vacuo and reverse phase column chromatography (a gradient from 5-30% acetonitrile in 0.1% aqueous formic acid) provided the title compound (14.7 mg, 25%). HPLC tR=1.71 min, LCMS 337.3 (M+1).
