Reaction of 4-chloro-5-sulfamoylphthalimide (4.54 g., 0.0174 mole) and 4-amino-1-[4-(2-propenyloxy)benzyl]piperidine (4.29 g., 0.0174 mole) in 100 ml. of n-pentanol at reflux temperature for 24 hrs. according to the procedure of Example 1(a) afforded crude 1,3-dioxoisoindole product. Purification was carried out by treating with methanol-decolorizing charcoal followed by trituration with ether to afford 4.8 g. (57%) of the 1,3-dioxoisoindole used without further purification below.
