Versuchsvorschrift

Into around-bottom flask, was placed a solution of 2-ethyl-4-methyl-5-(7-methyl-3,4,6,7-tetrahydropyrano[3,4-d]imidazol-2-yl)benzoic acid (compound 400.3, 30 mg, 0.10 mmol, 1.0 equiv) in DMF/DCM (5/5 mL). 4-(Piperidin-4-yl)benzonitrile hydrochloride (compound 1.5, 50 mg, 0.22 mmol, 2.2 equiv), EDC (40 mg, 2.0 equiv) and 4-dimethylaminopyridine (28 mg, 2.0 equiv) were added. The resulting solution was stiffed overnight at 25° C., then quenched with water (10 mL). The mixture was extracted with ethyl acetate (3×5 mL), and the combined organic layers was dried (Na2SO4), filtered and concentrated in vacuo. The residue was purified by silica gel chromatraphy with ethyl acetate/petroleum ether (2:1) as the eluent to obtain the title compound as a light yellow solid (3.2 mg, 7%). m/z (ES+) 469 (M+H)+.
