Procedure

To a solution of 2-(5-{3-[4-(4-Chloro-phenyl)-4-hydroxy-3,3-dimethyl-piperidin-1-yl]-propylidene}-5,11-dihydro-10-oxa-1-aza-dibenzo [a,d]cyclohepten-7-yloxy)-2-methyl-propionic acid (72 mg, 0.125 mmol) in dimethyl formamide (3 mL) was added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (48 mg, 0.25 mmol), 1-hydroxybenzotriazole (34 mg, 0.25 mmol), and ammonium hydroxide (170 μL, 0.50 mmol) and triethylamine (100 μL). Stir at rt 48 h. The mixture was poured into chloroform and washed with water. The organic phase was washed with additional water and brine; dried over magnesium sulfate, filtered and concentrated. The crude residue was purified by silica gel chromatography (methylene chloride—90:10 methylene chloride/methanol gradient) to yield the titled compound (22 mg, 31%).
