To a solution of 3-(3-bromomethylphenyl)-5-iso-butyl-N-tert-butylthiophene-2-sulfonamide (58 mg, 0.13 mmol; see step (e)) in dioxane (2.0 mL) was added imidazole (22 mg, 0.33 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 68% yield as a colourless syrup (38.4 mg, 0.088 mmol).
