Participants

Reaction Steps

To a suspension of 2 g (9.3 mmol) of product obtained in Example 28 in 20 ml of methanol are slowly added 0.2 g of palladium on carbon and 0.7 g of NaBH4. After the addition of NaBH4 has ended, the reaction is already complete. The reaction mixture is filtered through shell lime and washed with ethyl acetate, and the solvents are removed under reduced pressure. This gives 1.52 g (70%).
