Hydrochloric Acid → Tetrahydro-pyran-4-carboxylic acid [2-methyl-6-((2S,3'S)-2-methyl-[1,3']bipyrrolidinyl-1'-yl)-pyridin-3-yl]-amide

Participants

Reaction Steps

To a solution of 2-methyl-6-((2S,3′S)-2-methyl-[1,3′]bipyrrolidinyl-1′-yl)-pyridin-3-yl amine (0.1 g, 0.385 mmol) in DCM (3 mL) and DMF (1 mL), was added sequentially tetrahydro-2H-pyran-4-carboxlic acid (0.06 g, 0.461 mmol), N-methylmorpholine (0.127 mL, 1.16 mmol), 1-hydroxylbenzotriazole (HOBT) (0.068 g, 0.504 mmol), and EDCl.HCl (0.096 g, 0.504 mmol). The reaction mixture was stirred at room temperature for 16 hours. The reaction was quenched with a saturated aqueous solution of sodium bicarbonate (3 mL) and 15 mL of dichloromethane. The aqueous layer was extracted with dichloromethane (15 mL, 2×). The combined organic layers were washed with sodium bicarbonate (15 mL), brine (15 mL), dried over Na2SO4, and concentrated under vacuum. Purification by column chromatography on silica gel (0-10%) methanol in dichloromethane afforded 0.103 g (73%) of the title compound.
