1 ml of trifluoroacetic acid is added to 220 mg (0.4 mmol) of tert-butyl[2-(3-butoxy-3-o-tolyl-azetidin-1-yl)-1-(2-hydroxy-4-methoxybenzyl)-2-oxo-ethyl]carbamate in 2 ml of dichloromethane. After stirring for 1 hour at ambient temperature, the reaction medium is concentrated under vacuum. 250 mg of 2-amino-1-(3-butoxy-3-o-tolylazetidin-1-yl)-3-(2-hydroxy-4-methoxyphenyl)propan-1-one trifluoroacetate are obtained in the form of a yellow oil with a quantitative yield.
