Reaction Steps

4-[3-(3-Methylsulfonylphenyl)-1-spiro[5.5]undec-3-yl-ureidomethyl]benzoic acid (32.2 mg, 64.6 μmol) was dissolved in DMF (1 mL) and added N′-(3-dimethylaminopropyl)-N-ethylcarbodiimide hydrochloride (EDAC) (16.5 mg, 86 μmol) and 5-aminotetrazole.H2O (16,5 mg, 160 μmol). The mixture was stirred at 25° C. for 1 day and concentrated in vacuo. Brine (5 mL) was added to the residue followed by a mixture of ethanol and chloroform (1:2, 10 mL). The phases were separated and the aqueous layer was extracted with a mixture of ethanol and chloroform (1:2, 2×10 mL). The combined organic extracts were dried over MgSO4 and evaporated. The residue was purified by preparative HPLC affording the title compound.
