Reaction Steps

In a methanol/water (1/1) solution was dissolved 1.5 g of 10-tolyl-9-oxothioxanthenium nonafluorobutanesulfonate (Z-1) obtained in Synthesis Example 1, and the resulting solution was passed through an ion exchange resin (Amberlite IRA402Cl in which the anion was replaced by OH with an aqueous NaOH solution). After adding 1 g of 3,5-bistrifluoromethylbenzenesulfonic acid to the eluent, the solution was extracted with chloroform to obtain 1.7 g of 10-tolyl-9-oxothioxanthenium 3,5-bistrifluoromethylbenzenesulfonate (Z-2) which was a compound in which the counter salt was changed. 1H-NMR (400 MHz, CDCl3): σ 2.37 (s, 3H), 7.34 (d, 2H), 7.79 (m, 3H), 7.93 (m, 4H), 8.34 (m, 4H), 8.62 (d, 2H).
