실험 절차

A mixture of 100 mL of toluene, 11.6 g of 50% aqueous sodium hydroxide solution, and 10 mL of water was cooled in an ice bath and treated with 1.3 g of benzyltriethylammonium chloride and 12.0 g of diisopropyl P-(hydroxymethyl)phosphonate (prepared as in U.S. Pat. No. 5,272,128) and stirred vigorously. To this was added a solution of 15 g of the compound of Example 16 (2-trifluoromethyl-6-methylbenzenesulfonyl chloride) in 10 mL of toluene. The cooling bath was removed and the mixture stirred for one hour, then the layers were separated. The organic phase was washed with water (2×100 mL) and brine, then dried through calcium sulfate to yield 23 g of di-O-isopropyl P-[[(2-trifluoromethyl-6-methylphenyl)sulfonyloxy]methyl]phosphonate as a brown oil.
