反应条件: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Methyl 3-chloro-3-oxopropanoate (9.4 ml, 87 mmol) was added into a solution of N-allyl-4-fluorobenzenamine (12 g, 79 mmol), DIEA (15 ml, 87 mmol) and DMAP (0.97 mg, 7.9 mmol) in CH2Cl2 (200 mL) at 0° C. under nitrogen. The reaction was stirred at 0° C. for 1 hour. The reaction mixture was poured into ice and water, extracted with CH2Cl2, washed with saturated aqueous NaHCO3 and brine. The organic layer was dried with Na2SO4, filtered and concentrated. The residue was purified by flash column chromatography (50% EtOAc in hexane) to afford the product (18.3 g, 92% yield) as brown oil. extracted with CH2Cl2 washed with saturated aqueous NaHCO3 and brine The organic layer was dried with Na2SO4 filtered concentrated The residue was purified by flash column chromatography (50% EtOAc in hexane)

实验步骤: A suspension of 4-fluorobenzenamine (25 g, 225 mmol), 3-bromoprop-1-ene (19.0 ml, 225 mmol) and K2CO3 (31.1 g, 225 mmol) was stirred in THF (1 L) for 2 days. Water (20 mL) and EtOAc (1 L) were added into the reaction mixture. The organic layer was separated and washed with brine, dried with Na2SO4, filtered and concentrated. The residue was purified by flash column chromatography (20% EtOAc in hexane) to afford the product (16 g, 47.0% yield) as an orange oil.
