Procedure
The title compound was prepared from 2,4-dichloroquinazoline (50 mg, 0.251 mmol) and 4-methylaniline (32 mg, 0.30 mmol) by a procedure similar to example 1b and was isolated as white powder (15 mg, 30%). 1H NMR (CDCl3): 7.97-7.89 (m, 3H), 7.71 (d, J=6.6 Hz, 2H), 7.64 (ddd, J=8.4, 6.6 and 2.1 Hz, 1H), 7.33 (d, J=6.6 Hz, 2H), 2.47 (s, 3H).
