Reaction Conditions

Reaction Steps

A mixture of the compound of Example 2 (1.7 g, 4.1 mmol) and N,N-dimethylformamide dimethylacetal (0.9 g, 8.2 mmol) in DMF (6 mL) was stirred at 100° C. for 2 h. After cooling at room temperature, the reaction mixture was diluted with water (30 mL) and extracted with AcOEt (3×50 mL). The combined organic phases were washed with brine (2×50 mL), dried and evaporated to give 1-[(4-(3-dimethylaminopropenoyl)-2-methoxy-5-nitrophenoxy)methyl]-N-benzyloxycarbonyl-1-aminocyclopropane (1.9 g, yield: 95%) as a yellow solid.
