Procedure

To a solution of 3-[4-(3-hydroxy-propoxy)-3,5-dimethyl-phenyl]-1-((1aS,5aR)-1,1,2-trimethyl-1,1a,5,5a-tetrahydro-3-thia-cyclopropa[a]pentalen-4-yl)-propan-1-one (2.00 g, 4.85 mmol) in DCM (60 mL) and DIPEA (1.33 mL, 7.76 mmol) is added methane sulfonylchloride (0.452 mL, 582 μmol) at 0° C. The reaction mixture is stirred at 0° C. for 30 min. Another portion of methane sulfonylchloride (0.452 mL, 5.82 mmol) is added and stirring is continued 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 3-{2,6-dimethyl-4-[3-oxo-3-((1aS,5aR)-1,1,2-trimethyl-1,1a,5,5a-tetrahydro-3-thia-cyclopropa[a]pentalen-4-yl)-propyl]-phenoxy}-propyl ester (2.38 g) as a brown oil; LC-MS: tR=1.15 min, [M+1]+=491.34.
