Reaction Steps

To a N,N-dimethylformamide (1.5 ml) solution of 4-(4-Hydroxy-benzenesulfonyl)-2-methyl-3-(4-methyl-2,6,7-trioxa-bicyclo[2.2.2]oct-1-yl)-piperazine-1-carboxylic acid methylamide (compound of formula XLV, 0.31 g, 0.7 mmol) was added cesium carbonate (0.45 g) and 2-bromomethyl-4-fluoro-1-methyl-benzene (0.214 g, 1.05 mmol). The reaction mixture was stirred at about 45° C. for about 16 hours and then was allowed to cool and was diluted with ethyl acetate and washed with water. The organic layer was dried with sodium sulfate and concentrated in vacuo to give 0.377 g of a compound of formula XLIV.
