実験手順

A mixture of Intermediate C (100 mg, 0.37 mmol), 2-phenyl-1H-imidazole (533 mg, 3.7 mmol), Cut (35 mg, 0.18 mmol), trans-1,2-bis(methylamino)cyclo-hexane (52.5 mg, 0.07 mL, 0.37 mmol) and solid K2CO3 (511 mg, 3.7 mmol) in 2 mL of DMF was heated in a microwave reaction apparatus for 2 h at 200° C. After this time the reaction was transferred to a round bottom flask with the aid of EtOAc, then evaporated. The residue was purified by reverse-phase HPLC (PLRPS C-18 column, eluting with a gradient of 20-25% acetonitrile in water over 30 min) to give the title compound. LCMS: 377.2 m/z (M+H)+; ret. Time: 2.56 min (Analytical Method A); 1H NMR (400 MHz, CDCl3) δ: 7.9-7.8 (dd, 2H), 7.6-7.3 (m, 6H), 4.3 (dd, 1H), 3.8 (m, 1H), 3.4 (s, 3H), 1.9 (dd, 1H), 1.7 (dd, 1H), 1.05 (d, 3H), 0.9 (d, 3H) and 0.8 (d, 3H) ppm.
