1-(1,3-Dioxolan-2-yl)methanamine → 2-{[(1,3-Dioxolan-2-ylmethyl)-amino]-methyl}imidazo[1,2-a]pyridine-7-carbonitrile

Participants

Reaction Steps

To a DCM solution of 1-(1,3-dioxolan-2-yl)methanamine (799 mg, 7.83 mmol) was added 2-(chloromethyl)imidazo[1,2-a]pyridine-7-carbonitrile hydrochloride (Intermediate 17) (500 mg, 2.61 mmol). After heating to reflux for 1 hr, the reaction mixture was cooled room temperature, concentrated under reduced pressure, chromatographed on silica gel eluting with a gradient solvent mixture (5% MeOH-DCM to 15% MeOH-DCM) to give the title compound as oil (410 mg). LC/MS: m/z 259(M+H).
