Versuchsvorschrift
Followed the same procedure as that of step 2 in Example 91 with the use of (R)-2-(4-hydroxy-phenoxymethyl)-pyrrolidine-1-carboxylic acid tert-butyl ester (150 mg, 0.5 mmol) and 5-chloro-6-chloromethyl-benzo[1,3]dioxole (125 mg, 0.6 mmol) to afford the title product (80 mg, 40% yield).
