Procedure

A solution of ethyl 1-(4-chlorobenzyl)-7-hydroxy-1,2,3,4-tetrahydronaphthalen-2-ylcarbamate (0.128 g, 0.355 mmol) in DMF under N2 was treated with sodium hydride (0.014 g, 0.568 mmol) and the reaction was stirred for 30 minutes at room temperature. A solution of 2-(N-methylpropylsulfonamido)ethyl propane-1-sulfonate (0.102 g, 0.355 mmol) (see step 1) in DMF was added and the reaction mixture was stirred at ambient temperature over night. The mixture was portioned between ethyl acetate and water. The organic layer was washed with water, dried (MgSO4), filtrated and evaporated to afford brown/white crystals. After addition of a few drops of ethyl acetate/cyclohexane (1:4) a white precipitate formed. Yield 43 mg
