Versuchsvorschrift

To a solution of 6.72 g (45 mmol) of butylphenylamine in 50 ml of methylene chloride cooled to 10° C. was added slowly with stirring 6.67 g (22.5 mmol) of triphosgene in 40 ml of methylene chloride. The reaction was allowed to continue at room temperature for 27 hours. The solvent was evaporated and the residue extracted twice with n-hexane. The organic solution was concentrated in vacuo to yield 9.11 g (43.03 mmol) of a yellow oil (96%). 1H-NMR (CDCl3): δ 0.9 (m, 3H), 1.3 (m, 2H), 1.6 (m, 2H), 3.7 (m, 2H), 7.2-7.4 (m, 5H).
