Versuchsvorschrift
To a solution of 2-amino-3-bromopyridine (50.0 g, 289 mmol, 1 equiv) in dichloromethane (500 mL) was added dropwise ethoxycarbonyl isothiocyanate (39.0 g, 297 mmol, 1.03 equiv) at room temperature. After 2 h, dichloromethane was removed in vacuo to provide crude ethyl [(3-bromopyridin-2-yl) carbamothioyl]carbamate (88 g).
Aufarbeitung
- customdichloromethane was removed in vacuo
