A process for making a compound of formula (I) in which process the compound HC≡C-(CH<SUB>2</SUB>)<SUB>n</SUB>-NH<SUB>2 </SUB>is reacted with the compound R<SUB>1</SUB>-SO<SUB>2</SUB>Cl to produce an intermediate compound, which intermediate compound is then reacted with the compound of formula to produce the compound of formula (I), and compounds produced by the process of this invention. The terms R<SUB>1</SUB>, R<SUB>2</SUB>, R<SUB>3</SUB>, R<SUB>4 </SUB>and n have the definitions set forth in the specification.
