Procedure
A solution of 4-anilino-5-bromo-2-(4-iodoanilino)pyrimidine (Method 12; 200 mg, 0.40 mmol), N,N-dimethylpropargylamine (0.09 ml, 0.85 mmol) and tetrakis (triphenylphosphine)palladium (0) (25 mg, 0.02 mmol) in pyrrolidine (3 ml) was stirred for 60 hours and then heated at 80° C. for 2 hours. The mixture was diluted with DCM (10 ml) and silica (2 g) was added. Volatile material was removed by evaporation and the residue was loaded onto a Varian Mega Bond Elut column. Elution with 0–10% 2.0 M methanolic ammonia solution in DCM gave the product (30 mg, 17%). NMR: 2.2 (s, 6H), 3.4 (s, 2H), 7.2 (m, 3H), 7.4 (m, 2H), 7.6 (m, 4H), 8.2 (s, 1H), 8.6 (s, 1H), 9.5 (s, 1H); MS (MH+): 422.3, 424.3.
