Versuchsvorschrift

To a two phase solution of 2-fluoro-3-trifluoromethyl-phenylamine (2 g, 11.17 mmole) in dichloromethane (40 ml) and sodium bicarbonate (6.57 g, 78.19 mmole) in water (30 ml) at 0° C. was added dropwise a solution of thiophosgene (1.28 g, 11.17 mmole) in dichloromethane (10 ml). After 2 hrs, the organic layer was separated, washed sequentially with 1M NaHCO3, brine and water. The organic layer was dried over Na2SO4, filtered and concentrated to yield 2.2 g (91%) of product as a viscous liquid. MS (ESI+) m/z 221 (M+H)+.
