실험 절차

A solution of N-{5-[3-(aminomethyl)phenyl]-2,3-dihydro-1H-inden-2-yl}-2-propanesulfonamide (69 mg, 0.2 mmol) in dichloromethane (5 ml) was treated with triethylamine (40 mg, 0.4 mmol), followed by 4-chlorobutanoyl chloride (32 mg, 0.22 mmol) and the whole mix stirred at room temperature under argon for 1 h. The reaction mix was evaporated under reduced pressure to remove the dichloromethane and then dimethylformamide was added (5 ml) followed by potassium carbonate (60 mg, 0.43 mmol) and the mix stirred at 100° C. for 2 h. The reaction mix was cooled then partitioned between dichloromethane and 0.5M hydrochloric acid, and the organic layer was evaporated under reduced pressure to give a brown oil which was purified by column chromatography on a 1 g SCX column eluting from 0-50% ethyl acetate in 40-60° C. petroleum ether to give the title compound as a beige solid (16 mg, 19%).
