Participants

Reaction Steps

The procedure described in Example 120 was repeated using 2-chloroethyl isocyanate and 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) to give the title compound as a solid in 80% yield; NMR spectrum (DMSO-d6 @ 373K) 2.90 (s, 3H), 3.15-3.25 (q, 2H), 3.43-3.50 (t, 2H), 3.75-3.85 (t, 2H), 4.35-4,45 (t, 2H), 5.25, 6.35 (bs, 1H), 7.08-7.13 (d, 1H), 7.13-7.30 (m, 1H), 7.35-7.40 (m, 2H), 7.50-7.65 (m, 2H), 7.65-7.80 (m, 1H), 7.80-7.90 (t, 1H), 7.95 (d, 1H), 8.50 (s, 1H), 8.55-8.60 (d, 1H), 9.80 (s, 1H); Mass spectrum MH+ 541.3.
