Sodium Bicarbonate → HCID 86649011, Verbindung

To a solution of 3-chloro-5-[2-(methoxymethyl)pyrrolidin-1-yl]pyrazine-2-carbaldehyde (511 mg), (2R)-1-(benzylamino)-3-methoxypropan-2-ol (469 mg) and acetic acid (343 μL) in acetonitrile (10 mL) was added sodium triacetoxyborohydride (636 mg), and the mixture was stirred at room temperature for 14.5 hr. To the reaction mixture was added dropwise a saturated sodium hydrogen carbonate solution, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (solvent gradient: 10→50% ethyl acetate/hexane) to give the title compound (583 mg, 67%).
