Isobutyraldehyde → HCID 59625522, compound

Participants

Reaction Steps

To a solution of tert-butyl 4-amino-3,4-dihydroisoquinoline-2(1H)-carboxylate (840 mg) and 2-methylpropanal (256 mg) in dichloroethane (10 ml) were added acetic acid (203 mg) and sodium triacetoxyborohydride (931 mg). The mixture was stirred at room temperature for 1 hr. The mixture was neutralized with 6% aqueous sodium hydrogen carbonate. After partitioning, the organic layer was dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The residue was subjected to silica gel column chromatography, and the fraction eluted with ethyl acetate-hexane (1:1) was concentrated under reduced pressure to give the object compound (940 mg) as an oil.
