HCID 133706026-chloro-2-[1-[(4-chlorophenyl)methyl]-4-piperidinyl]-2,3-dihydro-1,3-dioxo-1H-isoindole-5-sulfonamide

Procedure

Reaction of 4-chloro-5-sulfamoylphthalimide (5.57 g., 0.0214 mole) and 4-amino-1-(4-chlorobenzyl)piperidine (4.8 g., 0.0214 mole) in 85 ml. of n-pentanol according to the procedure of Example 1(a) with heating at 130°-138° for a 48 hr. period afforded 7.07 g. (71%) m.p. 248°-250° (dec.) of the 1,3-dioxoisoindole product. A sample crystallized from dimethylformamide-methanol provided analytically pure 6-chloro-2-[1-[(4-chlorophenyl)methyl]-4-piperidinyl]-2,3-dihydro-1,3-dioxo-1H-isoindole-5-sulfonamide, m.p. 250°-251° (dec.).
