2-Chloro-4-(2-ethylanilino)pyrimidine (Reference Example A-5; 210 mg, 0.90 mmol) was dissolved in n-butanol (20 ml). To this solution was added a hot solution of 4-[3-(N,N-dimethyl)amino-2-hydroxypropoxy]aniline hydrochloride (Reference Example D-1; 229 mg, 0.81 mmol) in methanol (2 ml). The reaction mixture was heated at 100° C. for 18 hours, allowed to cool to ambient temperature and then evaporated onto silica (3 ml). The residue was purified by column chromatography eluting with 0–5% 2.0M methanolic ammonia solution in DCM to give the title product as a colourless solid (201 mg, 61%). NMR (300 MHz): 1.09 (t, 3H), 2.17 (s, 6H), 2.31 (m, 2H), 2.58 (q, 2H), 3.80 (m, 3H), 5.96 (d, 1H), 6.72 (d, 2H), 7.20 (m, 3H), 7.36 (d, 1H), 7.53 (d, 2H), 7.89 (d, 1H), 8.56 (s, 1H), 8.76 (s, 1H); m/z: (ES+) 408.3 (MH+)
