Versuchsvorschrift
To a solution of 24.5 g of 1-[3-chloro-5-(trifluoromethyl)phenyl]-2,2,2-trifluoroethanone (88 mmol, 1 eq) in 200 ml of toluene were added 13.6 g of m-(aminomethyl)benzylamine (100 mmol, 1.13 eq). After the addition of a catalytic amount of p-TsOH.H2O (˜100 mg), the mixture was refluxed on a water separator for 12 h (approx. 5 ml of water were removed). Thereafter, another 5.5 g of m-(aminomethyl)benzylamine (40 mmol) were added and the mixture was boiled for a further 11 h. Subsequently, the toluene was distilled off (760 Torr). The resulting crude product was distilled under high vacuum (30-105° C. at 0.5 Ton). Further distillation by means of a Vigreux column (b.p. 105-108° C. at 25 Torr) gives 16.0 g of 1-[3-chloro-5-(trifluoromethyl)phenyl]-2,2,2-trifluoroethanamine (58 mmol, 65%) as a clear liquid.
