Butyl Formate → 3-Fluoro-N-(5-formylaminomethyl-5,6,7,8-tetrahydro-naphthalen-2-yl)-benzenesulfonamide

Participants

Reaction Steps

A solution of 0.28 grams (0.837 mmoles) N-(5-aminomethyl-5,6,7,8-tetrahydro-naphthalen-2-yl)-3-fluoro-benzenesulfonamide in 6 mL n-butyl formate was heated under reflux for 1.5 hours. The solution was concentrated under reduced pressure. 3-Fluoro-N-(5-formylaminomethyl-5,6,7,8-tetrahydro-naphthalen-2-yl)-benzenesulfonamide was obtained by recrystallization of the residue from 2-propanol/ethyl ether to provide 0.27 grams (89%) of 3-fluoro-N-(5-formylaminomethyl-5,6,7,8-tetrahydro-naphthalen-2-yl)-benzenesulfonamide, m.p. 143-144° C., M+H=363
