HCID 62761-PentanolHCID 233124416-Chloro-2,3-dihydro-1,3-dioxo-2-[1-[[3-(trifluoromethyl)-phenyl]methyl]-4-piperidinyl]-1H-isoindole-5-sulfonamide

Procedure

Reaction of 4-chloro-5-sulfamoylphthalimide (10.1 g., 0.0386 mole) and 4-amino-1-(3-trifluoromethylbenzyl)piperidine (10.0 g., 0.0386 mole) in 200 ml. of n-pentanol according to the procedure of Example 1(a) afforded the crude 1,3-dioxoisoindole product purified by chromatography to yield 8.1 g. (42% yield) of 6-chloro-2,3-dihydro-1,3-dioxo-2-[1-[[3-(trifluoromethyl)phenyl]methyl]-4-piperidinyl]-1H-isoindole-5-sulfonamide. The NMR spectral data was consistent for the compound used without further purification below.
