To a solution of 4-(2,2-dimethyl-1,3-dioxan-5-yl)phenol (500 mg, 0.0026 moles) and 4,6 dichloro-5-nitropyrimidine (600 mg, 0.0028 mole) in dimethyl acetamide (10 ml) K2CO3 (776 mg, 0.00577 mole) was added −20° C. The reaction mixture was stirred for about 2 hours at −10° C. to −18° C. The reaction mixture was then poured into ice cold water and extracted with ethyl acetate. The organic extract was successively washed with water & brine, dried over sodium sulfate and evaporated under reduced pressure to yield crude product which was purified by column chromatography using 15% ethyl acetate in hexane as eluent to yield 500 mg product as pale yellow solid.
