Reaction Steps

A mixture of 8-(5-bromo-thiophene-2-sulfonyl)-2-(3-trifluoromethyl-phenyl)-1,3,8-triaza-spiro[4.5]dec-1-en-4-one (11.1 mg, 0.0212 mmol), 4-(N,N-dimethylaminocarbonyl)phenylboronic acid (8.0 mg, 0.041 mmol), Pd(PPh3)4 (3.8 mg, 0.0033 mmol) and Na2CO3 (22.0 mg, 0.208 mmol) in toluene (0.12 ml)-EtOH (0.12 ml)-H2O (0.12 ml) was stirred at 85° C. for 20 hours in a sealed test tube in an N2 atmosphere. The reaction mixture was cooled to room temperature and extracted with AcOEt. The organic layer was washed with a saturated aqueous NH4Cl solution, and then dried over MgSO4 and concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (AcOEt) to give N,N-dimethyl-4-{5-[4-oxo-2-(3-trifluoromethyl-phenyl)-1,3,8-triaza-spiro[4.5]dec-1-ene-8-sulfonyl]-thiophen-2-yl}-benzamide (9.7 mg, 77%).
