Reaction Steps

The procedure described in Example 63 was repeated using 5-[(1R)-2-amino-1-methylethoxy]-N-[3-chloro-4-(pyridin-2-ylmethoxy)phenyl]quinazolin-4-amine and (R)-(+)-α-hydroxy-γ-butyrolactone to give the title compound in 54% yield; NMR spectrum (DMSO-d6) 1.39 (d, 3H), 1.43-1.57 (m, 3H), 1.71-1.86 (m, 1H), 3.33-3.53 (m, 3H), 3.65-3.79 (m, 1H), 3.88-4.00 (m, 1H), 4.36 (t, 1H), 4.85-4.96 (m, 1H), 5.29 (s, 2H), 5.45 (d, 1H), 7.24 (d, 2H), 7.28-7.41 (m, 2H), 7.59 (t, 2H), 7.71 (t, 1H), 7.87 (t, 1H), 8.10-8.21 (m, 2H), 8.48 (s, 1H), 8.59 (d, 1H), 9.99 (s, 1H); Mass spectrum MH+ 537.9.
