Procedure

To a room temperature slurry of 1.03 g of nicotinoyl chloride hydrochloride in 20 ml of methylene chloride is added, via cannula, 2.0 g of product from Example 145 in 30 ml of methylene chloride. After 5 minutes, 2.05 g of triethylamine is added and the reaction stirred at room temperature for 72 hours. The solution is poured into saturated sodium bicarbonate and extracted with methylene chloride. The organic layer is washed with saturated sodium chloride, dried and concentrated in vacuo. The residue is purified by chromatography (silica gel: 40% ethyl acetate/hexane) to give 2.35 g of the desired product.
