Participants

Reaction Steps

1.58 ml (11.38 mmol) of triethylamine and 0.88 g (5.68 mmol) of 4-(trifluoromethyl)benzyl bromide, in solution in 5 ml of acetonitrile, are successively added at room temperature, with magnetic stirring and under an argon atmosphere, to a solution of 1 g (2.84 mmol) of 5-(8-amino-7-chloro-2,3-dihydro-1,4-benzodioxin-5-yl)-3-(piperidin-4-yl)-1,3,4-oxadiazol-2(3H)-one in 60 ml of acetonitrile and the mixture is stirred for 2 h. The solvent is evaporated under reduced pressure, the residue is taken up in chloroform, the solution is washed a number of times with water and dried and the solvent is evaporated under reduced pressure. The residue is crystallized from acetone and 1.14 g of white solid are obtained. Melting point: 198° C.
