    Abstract: The reaction of N-alkylimidazol with alkyl sulfonates, at room temperature, favors the production of 1,3-dialkylimidazolium alkane-sulfonates as crystalline solids at high yields. The alkane-sulfonate anions may be easily substituted by a series of other anions [BF4, PF6, PF3(CF2CF3)3, CF3SO3 and (CF3SO2)2N] through simple anion, salt, or acid reactions in water at room temperature. The extraction with dichloromethane, filtration, and evaporation of the solvent, allows the production of the desired ionic liquids at a yield of 80-95%. The purity of these ionic liquids (in some cases >99.4%) is performed using the intensity of 13C satellite signals from the magnetic resonance spectrums of the N-methyl imidazolium group as an internal standard.

  • Patent number: 6265428
    Abstract: Methods, compositions, and compounds for modulating the activity of an endothelin peptide are provided. The methods use compositions that contain compounds of formula (1): where X and Y are selected from groups that include O, S, and NH; and Ar1, Ar2 and Ar3 are independently selected from substituted or unsubstituted groups that include 5 to 6 membered aryl groups and heteroaryl groups that contain one or two heteroatom(s). The methods are effected by contacting endothelin receptors with one or more of the compounds or with compositions containing one or more of the compounds prior to, simultaneously with, or subsequent to contacting the receptors with an endothelin peptide.
