Reaction Steps

A solution of 4-(2-methoxy-4-(trifluoromethyl)phenyl)quinazoline-7-sulfonyl chloride (Intermediate DDDD; 2.040 g, 5.06 mmol) and thiazol-2-amine (2.54 g, 25.3 mmol) in 40 mL of MeCN was treated with 1-methylimidazole (0.496 ml, 5.06 mmol) and was heated to reflux with a heat gun, and then allowed to stir at room one hour. The reaction mixture was concentrated and the material was purified by silica gel column chromatography (0 to 100% EtOAc/heptane) to yield 4-(2-methoxy-4-(trifluoromethyl)phenyl)-N-(thiazol-2-yl)quinazoline-7-sulfonamide (1.230 g, 2.64 mmol, 52.1% yield). 1H NMR (acetonitrile-d3) δ ppm: 9.42 (s, 1H), 8.52 (s, 1H), 7.95 (d, J=8.8 Hz, 1H), 7.77 (d, J=8.7 Hz, 1H), 7.58 (d, J=7.4 Hz, 1H), 7.45-7.51 (m, 2H), 7.01 (d, J=4.8 Hz, 1H), 6.64 (d, J=4.7 Hz, 1H), 3.76 (s, 3H). m/z (ESI) 467.0 (M+H)+
