実験手順
To a solution of 3-chloroaniline (1.27 g, 10 mmol) in 1,2-dichloroethane (20 ml) were added molecular sieves (4 g, size 0.4 nM) and cyclopropanecarboxyaldehyde (0.7 g, 10 mmol). After stirring the mixture for 5 min at room temperature sodium triacetoxyborohydride (3.18 g, 15 mmol) and acetic acid (0.6 g, 10 mmol) were added. The reaction mixture was stirred at room temperature overnight. For workup dichloromethane (100 ml) and 1 M sodium bicarbonate solution (40 ml) were added and the mixture was shaken. The organic layer was separated, dried over magnesium sulfate and evaporated. The residue was purified using flash chromatography (heptane/ethyl acetate=9:1) to yield a colourless liquid (1.09 g, 60%); MS (EI): 181.1 (M+.).
