실험 절차
Tert-Butyl 4-(3-methyl-2-(phenylcarbamoyl)phenyl)-3-oxobutan-2-ylcarbamate (compound 4703) (4.61 g, 0.012 mol) was dissolved in HCl/MeOH (50 mL) and stirred at reflux for 30 min. The mixture was concentrated in vacuo and then saturated Na2CO3 solution was added to adjust PH to about 7-8. The resulting solid was collected by filtration and further dried in vacuo to afford the desired product, 3-(1-aminoethyl)-8-methyl-2-phenylisoquinolin-1(2H)-one (compound 4704) (2.9 g, 90% yield, where the ratio of isomers is S:R=5:1) as a white solid.
