To a solution of 0.18 grams (0.538 mmoles) N-(5-aminomethyl-5,6,7,8-tetrahydro-naphthalen-2-yl)-3-fluoro-benzenesulfonamide in 25 mL pyridine was added 0.052 grams (0.511 mmole) acetic anhydride. The reaction mixture was stirred at 23° C. for 4 hours. The mixture was diluted with water and extracted with ethyl acetate. The organic phase was washed with 0.5M hydrochloric acid, water, and saturated aqueous sodium chloride. The organic phase was dried (magnesium sulfate) and concentrated under reduced pressure. N-[6-(3-Fluoro-benzenesulfonylamino)-1,2,3,4-tetrahydro-naphthalen-1-ylmethyl]-acetamide was obtained as a crystalline solid from ethyl acetate/ethyl ether, 0.18 grams (89%), m.p. 136-137° C., M+H=377.
