1.50 g (10.67 mmol) of 4-chlorobenzaldehyde were dissolved in 20 ml of diethyl ether at 0° C., and 32.0 ml (16.00 mmol) of a 0.5N solution of cyclopropylmagnesium bromide in tetrahydrofuran were slowly added dropwise. Stirring at 0° C. for 1 h was followed by warming to RT, addition of water and ethyl acetate to the reaction solution, and separation of the phases. The organic phase was dried over sodium sulfate, the solid was filtered off, and the solvents were removed in vacuo. The crude product was purified by preparative HPLC (mobile phase: acetonitrile/water gradient) to result in 1.21 g (62% of theory) of the title compound.
