Participants

Reaction Steps

Dissolved in 4.0 ml of diethylformamide was 0.4 g of the 2-(4-benzylpiperazino)-4-methylpyrimidine-5-carboxylic acid obtained in Referential Example 3. At room temperature, 0.5 ml of phosphorus oxychloride was added dropwise. Thereafter, the contents were heated and reacted at 100° C. for 1.5 hours. After cooling, the reaction mixture was poured in an aqueous solution of sodium carbonate to neutralize same, followed by extraction with chloroform. After washing the chloroform layer with water, it was dried with anhydrous magnesium sulfate. Chloroform was distilled off under reduced pressure to obtain 0.29 g of the intended product (yield: 60%).
