Reaktionsschritte
[4-(Methoxy-methyl-carbamoyl)-cyclohexyl]-carbamic acid tert-butyl ester (7.50 g, 26.2 mmol) in dry ether (150 ml) was reduced with an excess LiAlH4. The reaction mixture was quenched by careful addition of water and extracted with CHCl3. The mixture was dried and concentrated under reduced pressure to give (4-formyl-cyclohexyl)-carbamic acid tert-butyl ester (6.30 g, 93%).
