0.44 g (3.4 mmol) of the crystal of N, N-dimethylchloromethyleneiminium chloride synthesized in Example I-101 was suspended in 10 mL of 1,4-dioxane, 0.72 g (2.00 mmol) 8 mmol) in 1,4-dioxane 4 mL was added dropwise at room temperature. When stirred at 80 ° C. for 30 minutes, a homogeneous solution was obtained. Sodium bicarbonate water and dichloromethane were added, the organic phase was separated, and the solvent was distilled off, whereby 0.78 g of triphenylmethyl chloride was obtained in a quantitative yield.
