Participants

Reaction Steps

Sodium hydride (12 mg) was added, while cooled with ice, to a dimethylformamide (1.2 ml) solution of the 4-chloro-N-{(1R)-1-[4-ethyl-5-(methylsulfonyl)-4H-1,2,4-triazol-3-yl]ethyl}benzenesulfonamide (Compound 182) (47 mg) obtained in Example 5 and n-propanol (0.027 ml). The mixture was stirred for 30 minutes at room temperature, and then stirred for 2 hours at 100° C. After the reaction mixture was cooled to room temperature, it was added to a saturated aqueous solution (5 ml) of ammonium chloride. The mixture was extracted with ethyl acetate (20 ml×2) and washed with a saturated aqueous solution (20 ml) of sodium chloride. The organic layer was dried over anhydrous magnesium sulfate, and then the solvent was distilled off under reduced pressure. The resulting residue was purified by silica gel flash column chromatography using a solvent mixture of methanol and chloroform to obtain Compound 183 (35 mg).
