Versuchsvorschrift
3-(tert-Butoxycarbonylamino)-1-(2-oxy-4-bromo-5-isoquinolinesulfonyl)pyrrolidine (Intermediate 3) can be obtained by using Intermediate 1 in the method of Example 6-1, Step A instead of Intermediate 1a, and then used in the method of Step B to obtain 3-(tert-butoxycarbonylamino)-1-(4-bromo-1-methoxy-5-isoquinolinesulfonyl)pyrrolidine (Intermediate 4), and then Intermediate 4 can be used in the method of Step C to obtain the title compound.
