実験手順

At 0° C., 13.1 g of 6-(2,4-difluorophenoxy)-5-indanylamine in 60 ml of pyridine was combined with 4.0 ml of methanesulfonyl chloride. After 3 hours at 0° C. and 16 hours at 20° C., the mixture was concentrated, the residue was taken up in chloroform, the solution was washed with 1N hydrochloric acid, and concentrated. Recrystallization of the residue from ethanol yielded 8.1 g of N-[6-(2,4-difluorophenoxy)-5-indanyl]methanesulfonamide, mp 85°-87° C.
