Reaction Steps

To a solution of 3-[4-(2-hydroxy-ethoxy)-3,5-dimethyl-phenyl]-1-(3,5,5-trimethyl-4,5,6,7-tetrahydro-benzo[c]thiophen-1-yl)-propan-1-one (130 mg, 0.325 mmol) in DCM (10 mL) and DIPEA (0.09 mL, 0.52 mmol) is added methane sulfonylchloride (0.03 mL, 0.39 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-{2,6-dimethyl-4-[3-oxo-3-(3,5,5-trimethyl-4,5,6,7-tetrahydro-benzo[c]thiophen-1-yl)-propyl]-phenoxy}-ethyl ester (165 mg) as a yellow oil; LC-MS: tR=1.17 min, [M+1]+=479.26.
