Yield	Reaction Conditions	Operation in experiment
	at 60℃; for 16h;	EXAMPLE 181A N-3-isoquinolinylacetamide 3-Aminoisoquinoline (495 mg, 3.44 mmol) was stirred in Ac2O (9 mL) at 60° for 16 hours. The mixture was cooled to room temperature and concentrated in vacuo to provide the title compound which was used in the next step without further purification.
	With triethylamine; In dichloromethane; at 20℃; for 3.5h;	Acetic anhydride (5.92 mL, 62.6 mmol) was added to a suspension of isoquinolin-3- amine (3.01 g, 20.9 mmol) and triethylamine (3.18 mL, 23.0 mmol) in CH2Cl2 (80 mL) at ambient temperature. The mixture was stirred 3.5 hours, then the volatiles were evaporated in vacuo. The residue was chased with toluene and concentrated in vacuo (3 x 25 mL) to provide the title compound (3.89 g) as a yellow solid. This material, which was found to also contain small quantities of acetic acid, was used without further purification. 1H NMR (300 MHz, DMSO-J6) delta 10.58 (s, IH), 9.13 (s, IH), 8.45 (s, IH), 8.04 (d, J= 7.8 Hz, IH), 7.88 (d, J= 8.2 Hz, IH), 7.69 (ddd, J= 8.2, 6.8, 1.2 Hz, IH), 7.52 (ddd, J= 7.9, 6.9, 1.0 Hz, IH), 2.13 (s, 3H).
