Procedure

5-[(1R)-2-amino-1-methylethoxy]-N-[3-chloro-4-(pyridin-2-ylmethoxy)phenyl]quinazolin-4-amine (obtained as described in Example 65, preparation of starting materials, 868 mg) was stirred in DCM (40 ml) with DIPEA (1 ml). N-(tert-butoxycarbonyl)sarcosine (400 mg) and HATU (800 mg) were added and mixture was stirred for 18 hours. Volatile material was removed by evaporation and the residue was purified by chromatography, eluting with increasing concentrations of methanol in ethyl acetate (0-10%). Evaporation of the appropriate fractions gave the title compound as a froth (0.50 g); NMR spectrum (DMSO-d6 @ 373k) 1.10 (s, 6H), 1.20 (s, 3H), 1.40-1.42 (d, 3H), 2.72 (s, 3H), 3.40-3.60 (d, 1H, (masked by H2O), 3.60-3.75 (q, 2H), 3.75-3.80 (d, 1H), 4.90-5.00 (bs, 1H), 5.30 (s, 2H), 7.28-7.34 (q, 2H), 7.34-7.40 (m, 1H), 7.42-7.46 (d, 1H), 7.50-7.62 (m, 2H), 7.85-7.91 (dt, 1H), 7.91-7.99 (m, 2H), 8.24-8.34 (bs, 1H), 8.57-8.62 (d, 1H), 8.75 (s, 1H), 10.60-10.70 (bs, 1H); Mass spectrum MH+ 607.
