실험 절차
The Suzuki coupling of (+,−) Cis propane-2-sulfonic acid [2-(4-iodo-phenyl)-cyclopentyl]-amide (225 mg, 0.57 mmol, prepared in example 17) and 3,5-difluorophenylboronic acid (108 mg, 0.69 mmol) was accomplished in a manner analogous to the procedure described in example 27. The reaction was worked up in a manner analogous to example 3. Purification by silica chromatography using a Chromatotron® was achieved eluting with methylene chloride to afford 110 mg (51%) of the title compound as a colorless oil.
