Procedure
To a solution of 1-(3-ethyl-5,5-dimethyl-4,5,6,7-tetrahydro-benzo[c]thiophen-1-yl)-3-[4-(3-hydroxy-propoxy)-3,5-dimethyl-phenyl]-propan-1-one (246 mg, 0.575 mmol) in THF (10 mL) and DIPEA (0.26 mL, 1.5 mmol) is added methane sulfonylchloride (0.08 mL, 1.00 mmol) at 0° C. The reaction mixture is stirred at 0° C. for 30 min. The reaction mixture is diluted with diethyl ether, washed with sat. aq. NaHCO3 solution followed by 10% aq. citric acid solution, dried over Na2SO4 and evaporated to give methanesulfonic acid 3-(4-[3-(3-ethyl-5,5-dimethyl-4,5,6,7-tetrahydro-benzo[c]thiophen-1-yl)-3-oxo-propyl]-2,6-dimethyl-phenoxy}-propyl ester (290 mg) as a brown resin; LC-MS: tR=1.20 min, [M+1]+=507.39.
