The procedure described in Example 1 was repeated using D-(−)-lactic acid and N-[3-chloro-4-(pyridin-2-ylmethoxy)phenyl]-5-[(1R)-1-methyl-2-(methylamino)ethoxy]quinazolin-4-amine (obtained as described in Example 2.3, preparation of starting materials) to give the title compound as a white solid in 26% yield; NMR spectrum (DMSO-d6 373K) 1.15 (d, 3H), 1.44 (d, 3H), 2.97 (s, 3H), 3.16 (m, 1H), 4.05 (dd, 1H), 4.43 (m, 1H), 5.16 (m, 1H), 5.27 (s, 2H), 7.23 (m, 2H), 7.35 (m, 2H), 7.59 (m, 2H), 7.70 (t, 1H), 7.84 (dt, 1H), 8.09 (d, 1H), 8.47 (s, 1H), 8.59 (d, 1H), 9.90 (s, 1H); Mass spectrum MH+ 522.
