A mixture of 3-dimethylamino-1-(2,4-dimethyl-thiazol-5-yl)-propenone (0.95 mmol, 0.19 g) and N-(4-dimethylamino-phenyl)-guanidine (2 mmol) in 2-methoxylethanol (5 mL) was added NaOH (40 mg). The reaction mixture was heated at 120° C. for 18 h. The solvent was evaporated and the residue was purified by chromatography, using EtOAc/PE to afford N,N-dimethyl-N′-{4-(2,4-dimethyl-thiazol-5-yl)-pyrimidin-2-yl}-benzene-1,4-diamine {119} (74 mg) as a reddish-brown solid. 1H-NMR (300 MHz, d6-DMSO) δ2.62 (s, 3H, CH3), 2.65 (s, 3H, CH3), 2.86 (s, 6H, CH3), 6.73 (m, 2H, Ph-H), 6.97 (d, 1H, J=5.1 Hz, pyrimidinyl-H), 7.56 (m, 2H, Ph-H), 8.44 (d, 1H, J=5.0 Hz, pyrimidinyl-H), 9.33 (s, 1H, NH). DE MALDI-TOF MS: {M+H}+=329.51 (C17H19N5S requires 325.43).
