Reaction Conditions

Reaction Steps

4 g 2-nitrobenzoic acid (23.93 mmol) and 2.42 g triethylamine were dissolved in 100 mL dichloromethane, mixed with one equivalent isobutyl chloroformate (3.27 g) at 5° C. and stirring was continued for 1 hour at room temperature. Then the mixture was cooled again to 5° C., 4.02 g 2,6-dimethoxybenzylamine was added and the mixture was stirred at room temperature until the reaction was complete. For workup, the mixture was diluted with dichloromethane, washed twice each with 10% citric acid, saturated NaHCO3 and saturated NaCl solution, dried with MgSO4, filtered and concentrated, yielding 7.5 g beige solids that were reacted further directly without any further workup.
