Reaction Steps

To a solution of N-(3,4-Dihydro-5-oxa-1,2a-diaza-acenaphthylen-2-yl)-benzenesulfonamide (125 mg, 0.40 mmol) in DMF (2.5 mL) was added 1-bromomethyl-4-trifluoromethyl-benzene (190 mg, 0.80 mmol) and potassium carbonate (55 mg). The resulting mixture was heated to 120° C. in a microwave reactor for 1 h. The resulting mixture was then diluted with EtOAc, washed with H2O and the organic layer was dried over Na2SO4, filtered, and concentrated in vacuo. The resultant residue was purified by flash column chromatography (SiO2), eluting with a hexanes-EtOAc gradient to yield N-(3,4-dihydro-5-oxa-1,2a-diaza-acenaphthylen-2-yl)-N-(4-trifluoromethyl-benzyl)-benzenesulfonamide as a crude residue (1st compound to elute off the column) The residue was purified by HPLC (reverse phase C-18 column, 45-100% acetonitrile/water containing 0.05% trifluoroacetic acid) to yield N-(3,4-dihydro-5-oxa-1,2a-diaza-acenaphthylen-2-yl)-N-(4-trifluoromethyl-benzyl)-benzenesulfonamide as its corresponding TFA salt.
