Versuchsvorschrift

To a solution of sodium nitrite (1 g, 0.02 mol), hexamethyldisilane (3 g, 0.02 mol), iodine (5 g, 0.02 mol) and benzyltriethylammonium chloride (0.3 g, 0.001 mol) in carbon tetrachloride (100 mL, 1 mol) was added a solution of (R)-2-(5-amino-6-chloro-1-oxoisoquinolin-2(1H)-yl)propyl acetate (2.3 g, 0.0070 mol) in methylene chloride (3 mL, 0.05 mol) at 0° C. The mixture was stirred at the same temperature for 40 minutes and then warmed to room temperature overnight. The mixture was purified by flash chromatography to afford the desired product as a brown oil.
