Yield:113207-59-3 96%

Reaction Conditions:

with 10% Pd/C;hydrogen in ethyl acetate at 20; under 2250.23 - 7500.75 Torr;Flow reactor;

Steps:

4.1.2. Catalytic nitro-group reduction (2). 4.1.2.1. Method A

General procedure: The solution of nitro-spiro[1,3-dioxolan-2,3′-indol]-2′(1′H)-one in ethyl acetate (2 mg/mL) was hydrogenated using continuous flow reactor H-Cube (ThalesNano Nanotechnology Inc., Hungary) under the following conditions: Pd/C (10 %), 3-10 bar H2, 1,0-2,0 mL/min, rt. After the reaction proceeded the solvent was removed in vacuum.
