反応手順

A mixture of 4,6-dichloro-pyrimidin-2-yl-amine (6.6 g, 40 mmol), 4-aminobenzyl alcohol (8.0 g, 65 mmol) and N,N-diisopropylethylamine (15 ml) in ethanol (200 ml) was heated under reflux for 72 hours. Concentration under reduced pressure provided a solid which was stirred with 1.0 M hydrochloric acid (200 ml) for 1 hour, filtered, dried under reduced pressure, stirred with ethyl acetate (200 ml) for 2 hours, filtered, and dissolved in methanol (300 ml). Aqueous sodium carbonate solution (1.0 M, 50 ml) was added. After stirring for 2 hours, volatiles were evaporated under reduced pressure and water (200 ml) was added. Filtration and drying provided [4-(2-amino-6-chloro-pyrimidin-4-yl-amino)-phenyl]-methanol (6.3 g, 63% yield) as a white powder.
