Procedure

To cyanuric chloride (0.180 g, 1 mmol) in 1,4-dioxane (1 mL) at about −10 to −20° C. was added N,N-diisopropylethylamine (DIEA) (0.19 mL, 1 mmol) in CH3CN (1 mL) and 3-fluoro-p-anisidine (0.14 g, 1 mmol) in CH3CN (1 mL) and stirred for about 1 hour. The reaction mixture was then stirred at room temperature for about 1 hour. Then a solution of cycloheptylamine (0.13 mL, 1 mmol) and DIEA (0.19 mL, 1 mmol) in CH3CN (0.5 mL) was added and the reaction mixture was stirred overnight at rt. Then, N-methyl-4(methylamino)piperidine (0.15 mL, 1 mmol) and DIEA (0.19 mL, 1 mmol) in CH3CN (0.5 mL) were added and the reaction mixture was refluxed overnight. The reaction mixture was worked-up using saturated sodium bicarbonate, and brine. The organic layer was separated and dried over sodium sulfate, filtered, and concentrated under reduced pressure. The crude material was purified by column chromatography (silica gel, 90:9:1 dichloromethane: methanol: conc. ammonium hydroxide) to give 158 (0.130 g, 28%); TLC (silica gel, 90:9:1, CH2Cl2, CH3OH, conc. NH4OH), Rf 0.26); 1H NMR (600 MHz, CDCl3, 55° C.) δ 7.74 (br s, 1H), 6.94 (br s, 1H), 6.81–6.84 (m, 2H), 4.83 (br resonance, 1H), 4.55 (s, 1H), 3.98 (s, 1H), 3.82 (s, 3H), 2.97 (s, 3H), 2.94 (br d, J=11.9 Hz, 2H), 2.29 (s, 3H), 2.06–2.10 (m, 2H), 1.93–1.97 (m, 2H), 1.84–1.90 (m, 2H), 1.44–1.66 (m, 12H).
