Reaction Steps

In a reactor were placed 1.00 g (3.0 m moles) of 4-chloro-2-(4,6-dimethoxypyrimidine-2-ylcarbonyl)acetanilide and 20 ml of ethanol. The reactor contents were cooled to 5° C. or less. Thereto was added 0.25 g (6.6 m moles) of sodium borohydride. The mixture was stirred at the same temperature for 1 hour. Then, the temperature was increased to room temperature. After the completion of the reaction, an aqueous ammonium chloride solution was added and the mixture was extracted with ethyl acetate. The organic layer was concentrated. The concentrate was purified by silica gel column chromatography (n-hexane/ethyl acetate=1/1) to obtain 0.69 g (2.0 m moles) of 4-chloro-2-(4,6-dimethoxypyrimidine-2-ylhydroxymethyl)acetanilide. Yield: 68%
