実験手順

8.6 g (0.060 mol) of 2,4-difluorobenzylamine are heated in an autoclave with 8 g (0.060 mol) of 2,5-dimethoxytetrahydrofuran for 2 hours at 250° C. The reaction mixture is cooled and then purified by vacuum distillation. 9.2 g (79% of theory) of a colourless oil which boils at 110°-114° C. at 16 mbar are obtained.
