Reaction Steps

To a mixture of 3.00 g (9.00 mmol) 4-[4-(1-carboxy-ethyl)-phenyl]-piperidine-1-carboxylic acid tert-butyl ester (IX.1) and 3.85 mL (22.5 mmol) DIPEA in 5 mL DMF, 4.33 g (13.5 mmol) TBTU are added. The mixture is stirred for 15 min at rt. After that time, 0.94 mL (13.5 mmol) cyclopropylamine are added and the mixture is stirred for 12 h at rt. After that time, water is added and the mixture is extracted with EtOAc.
