Procedure

To a solution of 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-ol (64.5 mg, 0.131 mmol) in N,N-dimethylormamide (2.5 ml) was added sodium hydride (6 mg, 0.158 mmol), 60% dispersion in mineral oil, then acetic acid 2-bromo-ethyl ester (17 μl, 0.158 mmol). The reaction stirred at room temperature overnight under a nitrogen atmosphere. The reaction was quenched the following day with water and diluted with ethyl acetate. The organic layer was washed twice with water, then brine. After the organic layer was dried over magnesium sulfate the solvent was distilled off under reduced pressure to give the title compound, 132 mg (100%).
