Procedure
2-(2-Pyridyl)ethanesulfonyl chloride hydrochloride (214 mg) was added to a solution of (2R)-1-(5-phenylthiophene-2-sulfonyl]-N-(2-tetrahydropyranyloxy)-2-piperazinecarboxamide (200 mg) and triethylamine (188 mg) in CHCl3 (3 ml) with cooling on an ice bath. The reaction mixture was stirred at ambient temperature for 1 hour. The mixture was concentrated in vacuo, and the residue was purified by SiO2 column chromatography eluted with MeOH in CHCl3 (1%) to give 184 mg of (2R)-1-(5-phenylthiophene-2-sulfonyl)-4-[2-(2-pyridyl)-ethanesulfonyl]-N-(2-tetrahydropyranyloxy)-2-piperazinecarboxamide as an amorphous powder.
