Procedure

606 mg of 3-[(RS)-2-oxiranyl]pyridine and 991 mg of (RS)-5-(3-aminobutyl)-2-thiophenecarboxamide were heated to 100° for 25 hours in 5 ml of DMSO. The reaction mixture was diluted with water and extracted three times with methylene chloride. The methylene chloride solutions were washed with water, dried and evaporated in a vacuum. Chromatography of the residue on silica gel with ether/methanol gave 149 mg of 5-[(RS)-3-[[(RS)-2-hydroxy-2-(3-pyridyl)ethyl]amino]butyl]-2-thiophenecarboxamide, ε201 =14420; ε268 =11310.
