The procedure described in Example 3 (preparation of starting materials) was repeated using (2S)-2-(methylamino)propan-1-ol (obtained as described in Chacchio et al., Tetrahedron, 1995, 51, 5689) and 2-chloro-4-[(5-fluoroquinazolin-4-yl)amino]phenol (obtained as described in Example 4.5, preparation of starting materials) to give 2-chloro-4-[(5-{[(2S)-2-(methylamino)propyl]oxy}quinazolin-4-yl)amino]phenol in >100% yield; NMR spectrum (DMSO-d6) 1.20 (d, 3H), 2.40 (s, 3H), 3.20 (m, 1H), 4.15 (dd, 1H), 4.30 (dd, 1H), 7.00 (d, 1H), 7.10 (d, 1H), 7.30 (d, 1H), 7.60 (dd, 1H), 7.70 (t, 1H), 8.00 (d, 1H), 8.50 (s, 1H); Mass spectrum MH+ 359.4.
