Procedure

2 ml of trifluoroacetic acid are added to 195 mg (0.53 mmol) of 3-(1-trityl-1H-imidazol-4-yl) propylamine dissolved in 8 ml of DCM and then immersed in an ice bath. After warming to room temperature, the reaction medium is stirred for 2 hours and the solvents are then evaporated off. The solid obtained is taken up in EtOAc and water. The aqueous phase is then concentrated and 110 mg of a white powder are obtained and used in the next step without further purification.
