(2R)-2-methoxypropanoic acid → (2R)-N-{(2R)-2-[(4-{[3-Chloro-4-(pyridin-2-ylmethoxy)phenyl]amino}quinazolin-5-yl)oxy]propyl}-2-methoxy-N-methylpropanamide

Participants

Reaction Steps

The procedure described in Example 1 was repeated using (R)-(+)-2-methoxypropionic 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 brown gum in 44% yield; NMR spectrum (DMSO-d6 373K) 1.11 (d, 3H), 1.37 (d, 3H), 2.97 (s, 3H), 3.09 (s, 3H), 3.38 (m, 1H), 4.17 (q, 1H), 4.26 (dd, 1H), 5.16 (m, 1H), 5.28 (s, 2H), 7.24 (m, 2H), 7.33 (d, 1H), 7.37 (dd, 1H), 7.56 (d, 1H), 7.64 (dd, 1H), 7.69 (t, 1H), 7.86 (dt, 1H), 8.13 (d, 1H), 8.44 (s, 1H), 8.59 (d, 1H), 9.89 (s, 1H); Mass spectrum MH+ 536.
