Reaction Steps

2-Chloro-4-(2,5-dimethylanilino)pyrimidine (Reference Example A-1; 250 mg, 1.07 mmol) was dissolved in n-butanol (5 ml) and 4-[3-(N,N-dimethyl)amino-2-hydroxypropoxy]aniline hydrochloride (Reference Example D-1; 295 mg, 1.07 mmol) was added. The resulting suspension was treated with methanol until all the solid dissolved. The reaction mixture was heated at 100° C. for 8 hours and allowed to cool to ambient temperature. The reaction mixture was then basified to pH 9–10 using methanolic ammonia and then evaporated onto silica (5 ml). The residue was purified by column chromatography eluting with methanol (15%):DCM:aqueous ammonia (1%). The resulting gum was recrystallized from acetonitrile to give the title product as a solid (104 mg, 24%).
