実験手順

A mixture of N-[6-(6-chloro-2-methoxy-pyrimidin-4-yl)-benzothiazol-2-yl]-acetamide (160 mg, 0.48 mmol), 2-(2,4-dichloro-phenyl)-ethylamine (362 μL, 2.4 mmol), and K2CO3 (359 mg, 2.6 mmol) in N-methylpyrrolidinone (2.6 mL) is heated to 140° C. Water (20 mL) is added after 1 hour of heating and extracted with EtOAc (20 mL). The organic extracts are combined and dried over magnesium sulfate, filtered and evaporated. This residue is subjected to chromatography on silica gel eluting with 90% ethyl acetate:heptane to afford a solid which is triturated with 1:1 methanol:ethyl acetate. The solid is collected to afford N-(6-{6-[2-(2,4-dichloro-phenyl)-ethylamino]-2-methoxy-pyrimidin-4-yl}-benzothiazol-2-yl)-acetamide [31 mg, 13%, Example 94]. LCMS RT=2.49 minutes, MS: 488 (M+H). IC50=11 nM
