Versuchsvorschrift

5-Amino-3-chloroisoquinoline (740 mg, 4.15 mmol) was suspended in toluene (20 mL) and treated with 20% w/v phosgene solution in toluene (9 mL) and triethylamine (5 mL). The mixture was refluxed overnight and was then concentrated in vacuo and used in the next step without further purification.
