실험 절차

To methyl 2-amino-5-iodobenzoate (i-a) (15 g, 54 mmol) was added 200 mL of CH2Cl2, followed by DIEA (9.4 mL, 54 mmol) and a catalytic amount of DMAP. Ethyl 4-chloro-4-oxobutanoate (Rc═Rd═H) (8.5 mL, 60 mmol) was added, and the reaction mixture was allowed to stir at room temperature overnight. The reaction mixture was then poured into 250 mL H2O, and the organic layer was washed with brine, dried over MgSO41 filtered, and concentrated in vacuo to afford ii-a (22 g, 99%) as a pale yellow solid: MS m/z═406 (M+H).
