Procedure

A solution of 2.54 gm (10 mMol) 5-(4-fluorobenzoyl)-amino-1H-indole and 1.7 gm (15.0 mMol) 1-methyl-4-piperidone in 20 mL 10% methanolic potassium hydroxide was heated to reflux for 3.5 hours and then allowed to stir without heating. After 18 hours the resultant suspension was filtered, the solid washed with methanol and then dried under reduced pressure to give 2.30 gm (65.8%) 5-(4-fluorobenzoyl)-amino-3-(1-methyl-1,2,3,6-tetrahydropyridin-4-yl)-1H-indole as a tan powder.
