Reaction Steps

Tetrahydrofuran-3-carboxylic acid (1.72 mL, 1.8 mmol), EDC hydrochloride (344 mg, 1.80 mmol) and 1-hydroxybenzotriazole monohydrate (276 mg, 1.80 mmol) were added to Compound 454 (125 mg, 0.450 mmol), followed by stirring at 60° C. for 3.5 hours. The reaction mixture was poured into a saturated aqueous solution of sodium hydrogencarbonate, followed by extraction with ethyl acetate. The organic layer was washed with a saturated aqueous solution of sodium chloride and dried over anhydrous magnesium sulfate, and then the solvent was distilled away under reduced pressure. The resulting residue was reslurried with diethyl ether to afford the entitled Compound 524 (142 mg, 84%).
