Reaction Steps

Methyl isocyanate (0.035 ml) was added slowly to a stirred solution of N-[3-chloro-4-(pyridin-2-ylmethoxy)phenyl]-5-[2-(methylamino)ethoxy]quinazolin-4-amine (obtained as described in Example 1, preparation of starting materials, 217 mg) in DCM (10 ml). The resulting solution was stirred for 2 hours and then evaporated. The residue was triturated with acetonitrile and the resulting solid washed with ether to give the title compound as a solid (205 mg, 83%); NMR spectrum (DMSO-d6 @ 373K) 2.85 (s, 3H), 2.95 (s, 3H), 3.75-3.85 (t, 2H), 4.35-4.45 (t, 2H), 5.25 (s, 2H), 5.90-6.00 (bs, 1H), 7.10-7.15 (d, 1H), 7.15-7.25 (d, 1H), 7.30-7.37 (t, 2H), 7.52-7.60 (m, 2H), 7.65-7.73 (t, 1H), 7.80-7.86 (m, 1H), 7.94-7.99 (d, 1H), 8.44 (s, 1,H), 8.55-8.60 (d, 1H), 9.80 (s, 1H); Mass spectrum MH+ 493.4.
