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-ethylimidazole (45.4 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 (6:94) as eluent to give the sub-title compound in 85% yield as a colourless syrup (61.2 mg, 0.134 mmol).
