3-Iodobenzonitrile (3.76 g, 16.41 mmol) dissolved in tetrahydrofuran (1.5 ml) was cooled to −30° C. A solution of isopropylmagnesium chloride in tetrahydrofuran (2 M, 8.84 ml, 17.67 mmol) was added dropwise at −30° C. over 25 min. The reaction mixture was cooled to −78° C. A solution of (E)-1-chloro-4(1-(2-nitrovinyl)cyclobutyl)benzene (3.0 g, 12.62 mmol) in tetrahydrofuran (0.5 ml) was added dropwise. Aqueous work-up yielded the desired product which was used without further purification for the next step. Yield: 3.3 g (8.71 mmol, 69%, purity: 90% by HPLC)
