Procedure
To a solution of 3-[3-chloro-4-(2-hydroxyethoxy)-5-methoxy-phenyl]-1-(3,5,5-trimethyl-4,5,6,7-tetrahydro-benzo[c]thiophen-1-yl)-propan-1-one (160 mg, 0.40 mmol) in DCM (10 mL) and DIPEA (0.11 mL, 0.64 mmol) is added methane sulfonylchloride (0.04 mL, 0.48 mmol) at 0° C. The reaction mixture is stirred at 0° C. for 30 min. The reaction mixture is diluted with DCM, washed with 0.1 N aq. NaOH followed by 10% aq. citric acid solution, dried over MgSO4 and evaporated to give methanesulfonic acid 2-{2-chloro-6-methoxy-4-[3-oxo-3-(3,5,5-trimethyl-4,5,6,7-tetrahydro-benzo[c]thiophen-1-yl)-propyl]-phenoxy}-ethyl ester (183 mg) as a yellow oil; LC-MS: tR=1.15 min, [M+1]+=515.15.
