Reaction Steps

To a solution of 4-chloro-quinazoline described in Preparation Example X-1 (8 mg, 0.049 mmol) in 1-methyl-2-pyrrolidone (0.5 mL) were added 4-tert-butyl-benzylamine (10 μl, 0.059 mmol) and N,N-diisopropylethylamine (17 μl, 0.098 mmol), and the solution was stirred for 5 hours at 160° C. The reaction mixture was directly purified by reverse phase high performance liquid chromatography (acetonitrile-water mobile phase (containing 0.1% trifluoroacetic acid) was used), and the title compound (16.5 mg, 0.041 mmol, 72%) was obtained as a trifluoroacetic acid salt.
