実験手順

This compound is synthesized according to Makosza, et al with some modifications (Makosza, M., et al, Tetrahedron (1974), 30: 3723). A solution of 4-chloronitrobenzene (31.5 g, 0.2 mol) in pyridine (100 mL) is added dropwise to a vigorously stirred suspension of KOH (fine powder 70.0 g) and α-methylbenzylcyanide (26.2 g, 0.2 mol) in pyridine (150 mL), with the reaction temperature being maintained at 10° C. The reaction mixture is stirred for 24 hours at 25° C., and poured onto an excess of HCl-ice mixture. The acidic aqueous mixture is extracted with benzene, the organic phase washed with brine, dried (Na2SO4), and the benzene evaporated under vacuum. A crude product 42.5 g (84 wt %) results and is recrystallized from isopropanol-petroleum ether to give Compound 7 as white crystals,
