To a solution of product from Example 23 (155 mg, 0.82 mmol) in methylene chloride (5 ml) was added N-methylmorpholine (0.180 ml, 1.64 mmol) followed by the product from Example 5 (200 mg, 0.82 mmol). The resulting mixture was stirred for 15 hours at room temperature. The solvent was removed in vacuo and the residue dissolved in ethyl acetate. The organic layer was washed with 1N hydrochloric acid, saturated sodium bicarbonate, saturated sodium chloride and dried over anhydrous sodium sulfate. The crude residue was purified by flash chromatography to give 170 mg (52%) of the product.
