The procedure described in Example 3 was repeated using 3-(chloromethyl)-5-ethylisoxazole and 2-hydroxy-N-[(2R)-2-({4-[(4-hydroxy-3-methylphenyl)amino]quinazolin-5-yl}oxy)propyl]-N-methylacetamide (obtained as described in Example 90, preparation of starting materials) to give the title compound as a white solid in 7% yield; NMR spectrum (DMSO-d6 373K) 1.44 (d, 3H), 2.22 (s, 3H), 2.42 (s, 3H), 2.98 (s, 3H), 3.58 (m, 1H), 4.17 (m, 3H), 5.11 (m, 1H), 5.15 (s, 2H), 6.29 (s, 1H), 7.07 (d, 1H), 7.11 (d, 1H), 7.33 (d, 1H), 7.57 (m, 2H), 7.69 (t, 1H), 8.44 (s, 1H), 9.83 (s, 1H); Mass spectrum MH+ 492.
