The procedure described in Example 3 (preparation of starting materials) was repeated using acetic acid and 2-methyl-4-({5-[2-(methylamino)ethoxy]quinazolin-4-yl}amino)phenol (obtained as described in Example 3, preparation of starting materials) to give N-[2-({4-[(4-hydroxy-3-methylphenyl)amino]quinazolin-5-yl}oxy)ethyl]-N-methylacetamide as a light brown solid in 100% yield; NMR spectrum (DMSO-d6) 1.90 (s, 3H), 2.16 (s, 3H), 3.02 (s, 3H), 3.85 (t, 2H), 4.45 (t, 2H), 6.82 (d, 1H), 7.18 (dd, 1H), 7.25 (d, 1H), 7.34 (m, 2H), 7.92 (t, 1H), 8.65 (s, 1H), 9.45 (s, 1H), 10.52 (s, 1H); Mass spectrum MH+ 367.
