Dimethylformamide → HCID 86752404, compound

Participants

Reaction Steps

To a solution of 500 mL of 10% dimethylformamide in benzene was added 58.6% NaH (41 g, 1.0 mol) cooled in an ice bath was added ethyl acetoacetate (130 g, 1.0 mol) was added. The reaction was stirred at room temperature for 30 minutes, and m-fluorobenzyl chloride (145 g, 1.0 mol) was added. The reaction was heated to reflux for 3 hours and gave an NaCl precipitate which was then removed by filtration. The filtrated was poured into H2O, acidified with concentrated HCl and was extracted with a mixture of ether and benzene. The organic layer was washed with H2O, brine, dried over Na2SO4 and concentrated in vacuo. The crude product was purified by distillation (112-119° C./25 mmHg) to give compound A (133 g, 56%).
