To a 0° C. solution of 5.24 g of 2-(2-aminoethyl)pyridine, 13.22 ml of pyridine and 50 ml of methylene chloride is added, dropwise, 15 g of product from Example 53 in 150 ml of methylene chloride. The reaction is stirred at 0° C. for 4 hours followed by 68 hours at room temperature. The reaction is diluted with chloroform, washed with saturated sodium bicarbonate, water and saturated sodium chloride, dried and concentrated in vacuo. The residue is purified by column chromatography (silica gel:75-100% ethyl acetate/hexane) to give 8.3 g of the desired product as colorless prisms.
