Participants

Reaction Steps

90 mg (0.26 mmol) of 2-chloro-4-(methylsulfonyl)-3-[(2,2,2-trifluoroethoxy)methyl]benzoic acid and 45 mg (0.26 mmol) of 5-benzyl-1,3,4-oxadiazol-2-amine are dissolved at room temperature (RT) in 8 ml of CH2Cl2. Then 248 mg (0.398 mmol) of 2,4,6-tripropyl-1,3,5,2,4,6-trioxatriphosphinane 2,4,6-trioxide (50% solution in THF) are added, the mixture is stirred at RT for one hour and then 0.181 ml (1.3 mmol) of triethylamine, 6 mg (0.052 mmol) of 4-dimethylaminopyridine are added. Then the mixture is stirred at RT for 20 h and washed twice with 4 ml each time of water, dried over Na2SO4 and concentrated. The residue is purified by column chromatography (prep. HPLC; acetonitrile/water). Yield 70 mg (45%).
