Yield: 80%
Reaction Conditions:
with palladium on activated charcoal in tetrahydrofuran at 50; under 13446.2 Torr;
Steps:
1-3 Step 1-3: Reduction of nitro product 2
As shown in the above reaction scheme, after the product 2 was dissolved in THF,After adding the metal catalyst Pd / C into the hydrogenation tank,The hydrogenation reaction was carried out by heating and stirring at a pressure of 260 psi (the amount of the visible material was adjusted), and the hydrogenation temperature was 50 ° C.The reaction can be carried out using a TLC test piece (eluent: ethyl acetate: n-hexane = 1: 1, Rf = 0.16) to confirm whether the reaction is complete. After the reaction was complete, the Pd / C was filtered,The reaction solution was poured into 1200 ml of n-hexane to precipitate a solid. Filter to collect solids,And dried in a vacuum oven to obtain 30 g of product 3: Yield 80%.
