Participants

Reaction Steps

A stirred solution of 4-chloro-6-hydroxy-2-(2-propoxyphenyl)pyrimidine (0.43 g) and ethanolamine (0.3 g) in n-butanol (8 ml) was heated under reflux for 4 hours. The cooled reaction mixture was evaporated under reduced pressure to yield a residue which was washed with diethyl ether and then eluted from silica with chloroform: methanol (gradient elution). The combined fractions containing product were evaporated under reduced pressure to yield a crude product which was recrystallised from isopropanol:diethyl ether to yield the title compound, 0.28 g, m.p. 164.5°-65.5° C.
