Procedure
5.5 g of ethyl 1-(4-nitrophenyl)cyclobutanecarboxylate are dissolved in 55 ml of tetrahydrofuran, 2 g of 5% Pd/C (52.3% of water) are added, and the mixture is stirred at 23° C. under a hydrogen atmosphere for 1 h. After aeration, insoluble material is filtered off, and the filtrate is evaporated to dryness in vacuo. Yield: 4.3 g (89%) of ethyl 1-(4-aminophenyl)cyclobutanecarboxylate; LC-MS retention time: 2.05 min (“nonpolar” gradient).
