Participants

Reaction Steps

(S)-1-(Azetidin-1-yl)-3-methylbutan-2-amine (Compound U) (0.420 g, 2.95 mmol) and acetaldehyde (0.166 mL, 2.95 mmol) was mixed in DCM (10 mL). Sodium triacetoxyhydroborate (0.813 g, 3.84 mmol) was added in small portions and the resultant mixture was stirred at rt for 5 h. Water was added and the pH was adjusted to pH9. The water phase was extracted with DCM (4×50 mL). The combined organic layers were combined and washed with brine, passed through phase separator and evaporated under reduced pressure to give the title compound (0.1 g, 20%). The obtained crude product was used without further purification. LCMS (M+H)+: 171.
