Abstract
3-(2-Dialkylaminoethyl)-1,2-benzisoxazoles (2) are accessible by direct cyc lization of the corresponding Mannich bases oxime acetates (11) in refluxin g benzene in the presence of anhydrous potassium carbonate. The previously known methods for ring closure to 1,2-benzisoxazole were ineffective for th is class of pharmacologically relevant compounds.
