To a mixture of ethyl 4-chloro-6-(6-(methoxymethyl)pyridin-3-yl)quinoline-3- carboxylate (2 g, 5.61 mmol) and (5)-tetrahydro-2H-pyran-3-amine hydrochloride (0.926 g, 6.73 mmol) in DMF (10 ml) was added DIPEA (3.5 ml, 20.04 mmol) and the solution stirred at 80C for three h then allowed to cool. The reaction mixture was stirred with water (100 ml) and the solid was filtered off, washed thoroughly with water and sucked dry. The crude product was purified by FCC, elution gradient 0 to 3% 2N methanolic ammonia in DCM and pure fractions were evaporated to dryness to afford (5)-ethyl 6-(6-(methoxymethyl)pyridin-3-yl)-4- ((tetrahydro-2H-pyran-3-yl)amino)quinoline-3-carboxylate (1.640 g, 69.4 %) as a white solid.
