Procedure

1-(4-Cyclohex-1-enylphenyl)-3-(3,5-dichlorophenyl)-1-{4-[1-hydroxy-2-(2H-tetrazol-5-yl)ethyl]benzyl}urea (100 mg, 0.17 mmol) was dissolved in DCM (1 ml) and triethyl amine (27 μl, 0.195 mmol) was added. The mixture was cooled to 0° C. and methansulphonyl chloride (15 μl, 0.195 mmol) was added followed by 1,8-diazabicyclo[5,4,0]-undec-7-ene (29 μl, 0.195 mmol). The mixture was stirred at 0° C. for 2 hours, and at room temperature overnight, then diluted with DCM (20 ml) and washed with brine (20 ml). The organic solution was dried with anhydrous sodium sulphate and evaporated to dryness, to give pure title material as a white powder. Yield: 113 mg (100%).
