Abstract

Abstract The 1, 3-dipolar cycloaddition reaction of 1-methyl-and 1-(2-phenylethyl)-1, 2, 3, 4- tetrahydropyridines 7 with organic azides 8 afforded the respective 1-substituted- piperidylidene-2-sulfon (cyan) amides 9. Nitration of the 1-(2-phenylethyl) analogue 9o yielded the 1-[2-(4-nitrophenyl) ethyl] derivative 9r which on reduction with palladium-on- charcoal and hydrazine gave the 1-[2-(4-aminophenyl) ethyl] analogue 9s.
