Conditions

Temperature: 130 °C

Procedure

A mixture of triphenylsulfonium iodide (390 mg; 1 mmol) and trimethyl phosphate (1 g) was stirred at 130° C. for 3 hours. Subsequently, the homogenous solution was cooled, and the thus-obtained solid matter was washed with IPA, to thereby yield 280 mg of the target compound as white crystals (yield: 72.2%). The anion content of the resultant compound was determined by ion chromatography. The iodide anion content was determined to be not greater than 50 ppm.
