To a solution of 2,4,6-trimethylphenol (1.03 g) in N,N-dimethylformamide (20 ml) was added sodium hydride (60% in oil, 0.30 g), and stirred at ambient temperature for 5 minutes. To the solution was added 4-chloro-6-(3,4-dimethoxyphenyl)-2-methylpyrimidine (2.0 g), and the mixture was stirred at ambient temperature for 18 hours. The solution was poured into water (300 ml), and extracted with ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate and evaporated. The residue was chromatographed on silica gel eluting with chloroform to give 6-(3,4-dimethoxyphenyl)-2-methyl-4-(2,4,6-trimethylphenoxy)pyrimidine (1.96 g).
