Reaction Conditions

Reaction Steps

Methylamine (3 ml of a 33% solution in ethanol) and then triethylamine (0.159 ml, 1.1 mmol) was added to sulphanilyl fluoride (200 mg, 1.1 mmol), and the mixture heated at 80° C. for 6 hours then at ambient temperature for 18 hours. The volatiles were removed by evaporation and the residue azeotroped with toluene to give the title compound (160 mg, 76%). NMR: 2.30 (s, 3H), 5.85 (s, 2H), 6.60 (d, 2H), 7.39 (d, 2H); m/z: 187 [MH]+.
