Reaktionsschritte

2.9 g of methyl 2-hydroxy-3,3-dimethybutyrate, 4.1 g of 4,6 -dimethyl-2-methylsulfonylpyrimidine and 3.3 g of potassium carbonate were added to 50 ml of N,N-dimethylformamide, and the mixture was stirred at 100° C. for 4 hours. The reaction solution was cooled to room temperature, poured into water and extracted with 100 ml of ethyl acetate. The organic layer was washed twice with a sodium chloride aqueous solution, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The liquid substance thereby obtained was purified by silica gel column chromatography (eluent: hexane/ethyl acetate =6/1) to obtain 4.2 g of the desired product.
