実験手順

To a solution of 3-amino-3-(3-nitrophenyl)propanoic acid (20.00 g; 95.15 mmol; 1.00 eq.) in MeOH (300 mL) was added thionyl chloride (50.00 ml; 761.22 mmol; 8.00 eq.) at 0° C. slowly. Then the mixture was warmed to room temperature and stirred overnight. The reaction mixture was evaporated and the crude product was purified by flash chromatography on silica gel (MeOH:DCM=15:85) to obtain 20 g of the title compound. LCMS [225 (M+1)].
