Procedure

200 mg (0.85 mmol) of 2-chloro-4-(methylsulfonyl)benzoic acid and 167 mg (0.85 mmol) of 4-(4-chlorophenyl)-1,2,5-oxadiazol-3-ylamine are dissolved in 24 ml of CH2Cl2 at RT and treated with 0.12 ml (0.85 mmol) of triethylamine, 21 mg (0.17 mmol) of DMAP and 1814 mg (1.28 mmol) of 2,4,6-tripropyl-1,3,5,2,4,6-trioxatriphosphinane 2,4,6-trioxide (50% solution in THF). The reaction mixture is stirred for 30 h at RT and subsequently washed twice with in each case 5 ml of water. The organic phase is dried over Na2SO4 and evaporated. The residue is purified by column chromatography (silica gel, heptane/ethyl acetate). Yield 140 mg (36%).
