Reaction Steps

To a solution of 3-(3-bromomethylphenyl)-5-iso-butyl-N-tert-butylthiophene-2-sulfonamide (70 mg, 0.158 mmol; see Example 1(e)) in dioxane (2.0 mL) was added 2-butylimidazole (58.7 mg, 0.473 mmol) and the reaction mixture was stirred for 1 h at 80° C. The reaction mixture was concentrated in vacuo and the residue was purified by flash chromatography using MeOH:CH2Cl2 (5:95) as eluent to give the sub-title compound in 55% yield as a colourless syrup (42.1 mg, 0.087 mmol).
