Allylamine → HCID 52937224, compound

Temperature

90 °C

A mixture of 1-chloropent-4-en-2-ol (23.40 g, 194.06 mmol, 1.00 Eq) and prop-2-en-1-amine (33.00 g, 578.03 mmol, 2.98 Eq) was stirred at 90° C. for 16 hr. The mixture was cooled to 25° C. and concentrated in reduced pressure at 60° C. The residue was poured into ice-water (w/w=1/1) (150 mL) and stirred for 20 min. The aqueous phase was extracted with EA. The combined organic phase was washed with saturated brine (200 mL*2), dried with anhydrous Na2SO4, filtered and concentrated in vacuum. The residue was purified by silica gel chromatography (DCM:MeOH=30/1 to 10/1) to afford 1-(allylamino)pent-4-en-2-ol (16.00 g, 113.31 mmol, 58.39% yield) as yellow oil.
