N-octylacetamide

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Dimethylcarbamyl chloride (6.29 g, 58.4 mmol) was added slowly to 10.0 g (58.4 mmol) of N-octyl acetamide in 10 mL of dry toluene and the solution was refluxed under a nitrogen atmosphere for 16 h. The volatile materials were removed on a rotary evaporator and in vacuo. The residue, dissolved dichloromethane (30 mL), was stirred strongly for 30 min with a solution of 2.34 g (58.4 mmol) of sodium hydroxide in 40 mL of water. Calcium carbonate (2.34 g) was added to the mixture and it was stirred an additional 30 min. The organic phase was separated and the aqueous phase was washed with dichloromethane (30 mL×3). The combined organic phases were dried (calcium carbonate) and the volatile materials were removed on a rotary evaporator. The residue was distilled at 72-77° C./0.25 Torr to yield 7.1 g (61%) of product (purity 99% by GC).

Procedure: Dimethylcarbamyl chloride (6.86 g, 63.7 mmol) was added slowly to 10.0 g (63.7 mmol) of N-octyl acetamide in 10 mL of dry toluene and the solution was refluxed under a nitrogen atmosphere for 16 h. The volatile materials were removed on a rotary evaporator in vacuo. The residue, dissolved 30 mL of dichloromethane, was stirred vigorously with a solution of 2.55 g (63.7 mmol) of sodium hydroxide in 40 mL of water for 30 min. Calcium carbonate (2.55 g) was added to the mixture and stirring was continued for an additional 30 min. The organic phase was separated and the aqueous phase was extracted with dichloromethane (30 mL×3). The combined organic phases were dried (calcium carbonate) and the solvent was removed on a rotary evaporator.
