Reaction Steps
A solution of 3-(3,5-difluorophenyl)propylamine (0.0327 mol) and triethylamine (0.072 mol) in tetrahydrofuran (20 ml) was added dropwise to a solution of thiophosgene (0.0392 mol) in tetrahydrofuran at 0°. The reaction was stirred 2 hours at room temperature then ethyl ether was added and the mixture filtered. The filtrate was concentrated and distilled (Kugelrohr) to yield 3.8 g (55%) of a yellow oil.
