Reaction Steps

To a solution of 2-[[6-[(2R)-2-methylpyrrolidin-1-yl]-4-pyrrolidin-3-yl-2-pyridyl]amino]pyridine-4-carbonitrile hydrochloride (160 mg, 0.415 mmol) in methanol (3.0 mL) was added tetrahydropyran-4-carbaldehyde (0.086 mL, 0.831 mmol, 2.0 equiv.). It was heated @ 50° C. overnight. After cooling to room temperature, sodium triacetoxyborohydride (278.2 mg, 1.247 mmol, 3.0 equiv.) was added in portions. After 3 h, more sodium triacetoxyborohydride (278.2 mg, 1.247 mmol, 3.0 equiv.) was added, stirred @ rt for another o/n. It was quenched with 1N NaHCO3, extracted with EtOAc (2×20 mL), dried over Na2SO4, filtered, concentrated in vacuo, and purified by HPLC to afford 15.5 mg (8.3%) of product as yellow gum. LC-MS: m/z=447 (M+H+).
