In the manner described in Example 14, 6-methanesulfonamido-2-(4-piperidyl)-indan-1-one hydrochloride (0.20 g, 0.58 mmol), 5-(2-bromoethyl)benzofurazan (0.395 g, 1.74 mmol), sodium bicarbonate (0.146 g, 1.74 mmol) and potassium iodide (20 mg), in 20 mL of acetonitrile were heated under reflux for 30 hours. After purification by flask column chromatography on silica gel eluting with 5% methanol in chloroform saturated with ammonia (gas), and treatment with ethanol HCl, crystallization from methanol gave the title compound as a white solid, mp 214°-217° C.
