실험 절차

To a solution of 1.51 g of N-(1-benzyloxy-2-oxo-2,3,4,7-tetrahydro-1H-azepin-3-(R)-yl)-4-(4-chloro-phenoxy)-benzenesulfonamide from Example 1 Step E in 20 mL of methylsulfoxide (DMSO) was added 2.9 g of Cs2CO3(s) and 1.2 g of 4-(2-chloroethyl)-morpholine hydrochloride. The mixture was heated to 50° C. for 1 hour. The reaction was cooled, and then dissolved with ethyl acetate. The organic layer was washed with NH4Cl(aq) and NaCl(aq) solutions. The aqueous layers were re-extracted with ethyl acetate, and the organic layers were combined and dried over Na2SO4(s). Filtration and solvent removal was followed by column chromatography on silica gel using a hexanes-ethyl acetate gradient. Obtained 1.48 g of a pale brown oil (80% yield). MS: 612 (M+H).
