Participants

Reaction Steps

To a solution of N-[4-chloro-3-(trifluoromethyl)phenyl]-7-hydroxy-1,2,3,4-tetrahydronaphthalene-2-carboxamide (64 mg, 0.17 mmol) and 4-chloro-2-(4,5-dihydro-1H-imidazol-2-yl)pyridine (35 mg, 0.19 mmol) in DMF (1.70 mL) was added Cs2CO3 (170 mg, 0.52 mmol). The mixture was irradiated in a microwave for 200 sec at 200° C. Water was added, and the mixture was extracted with EtOAc. The organic solution was washed with water (3×) and brine, dried over Na2SO4, filtered and evaporated. The residue was purified by column chromatography. The product was dissolved in MeOH, and 2.0M HCl in Et2O was added. The solvents were evaporated to give I-36 as a white solid (59 mg, 58%). 1H NMR (300 MHz, CD3OD): δ 8.62 (d, 1H), 8.17 (d, 1H), 7.82-7.78 (m, 1H), 7.63 (d, 1H), 7.53 (d, 1H), 7.25 (d, 1H), 7.21-7.18 (m, 1H), 6.96-6.91 (m, 2H), 4.11 (s, 4H), 3.14-2.82 (m, 5H), 2.24-2.16 (m, 1H), and 2.01-2.90 (m, 1H). LCMS: (FA) ES+ 516.2, ES− 513.2.
