Reaction Steps
According to the procedure for the preparation of Intermediate 206.4, Intermediate 213.1 (1.02 g, 1.74 mmol) was converted to the chloro intermediate, which was displaced with di-tert-butyl (6-aminoisoquinolin-1-yl)imidodicarbonate (688 mg, 1.91 mmol) to afford after flash chromatography (0 to 60% EtOAc/hexanes gradient) 1.47 g of Intermediate 213.2 as a pale yellow solid.
