Procedure
4-(3-(4-(trifluoromethoxy)phenoxy)azetidin-1-yl)butyric acid (412 mg, 1.29 mmol) was dissolved in thionyl chloride, raised the temperature to reflux for 3 h, spun dry, residuals were washed by an appropriate amount of ethyl ether, generated 421 mg target product, yield was 97%, directly put to the next reaction step.
