Versuchsvorschrift
Part B: To a solution of 1-[2-((tert-butoxycarbonyl)amino)ethyl]-3-(4-chlorophenyl)-4,5-dihydro-4-phenyl-1H-pyrazole (1.91 gram, 4.8 mmol) in dichloromethane (50 ml) was added trifluoroacetic acid (5 ml) and the resulting solution was stirred at room temperature for 5 hours. After concentration in vacuo the residue was dissolved in ethylacetate and washed with 2 N sodium hydroxide solution. The ethyl acetate layer was dried over magnesium sulfate, filtered and concentrated in vacuo to afford 1-(2-aminoethyl)-3-(4-chlorophenyl)-4,5-dihydro-4-phenyl-1H-pyrazole (1.44 gram, quantitative yield) as an oil.
