10 ml of trifluoroacetic acid are added to a solution containing 1.4 g (2.8 mmol) of tert-butyl[1-(3-butoxy-3-o-tolylazetidine-1-carbonyl)-2-hydroxy-2-(4-methoxy-phenyl)ethyl]carbamate in 20 ml of dichloromethane. After stirring for 1 hour at ambient temperature, the reaction medium is concentrated. 1.5 g of 2-amino-1-(3-butoxy-3-o-tolylazetidin-1-yl)-3-hydroxy-3-(4-methoxy-phenyl)propan-1-one trifluoroacetate are obtained in the form of a beige powder with a quantitative yield.
