Procedure
1-Benzhydryl-3-fluoroazetidine-3-carbonitrile (3.5 g, 1.0 eq.) was dissolved in ethanol, and aq. NaOH solution (1N) was added. The reaction mixture was refluxed for 5 h, then was allowed to cool to room temperature, at which temperature, it was acidified with dilute HCl (pH=3) and extracted with ethyl acetate (50 mL×3). The combined organic layers were washed with brine, dried over sodium sulfate and concentrated under reduced pressure to obtain 0.5 g of 1-benzhydryl-3-fluoroazetidine-3-carboxylic acid (13% yield). The product was used in the next step without further purification.
