Versuchsvorschrift
To a solution of (R)-ethyl 4-(3′-chlorobiphenyl-4-yl)-3-(2-ethoxy-2-oxoacetamido)butanoate (450 mg, 1.08 mmol) in MeOH (24 mL) is added a solution of 50% wt hydrazine (0.068 ml, 1.08 mmol) in MeOH (10 mL) at −20° C. After stirring for 18 hours at room temperature, the reaction mixture is concentrated under reduced pressure to give (R)-ethyl 4-(3′-chlorobiphenyl-4-yl)-3-(2-hydrazinyl-2-oxoacetamido)butanoate (412 mg). HPLC retention time=1.76 minutes (condition A); MS (m+1)=404.1
