2,2-dimethylpentanamide

Conditions: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A stirred suspension of 2,2-dimethyl valeramide (35 g, 271 mmol) in ethyl acetate (200 ml) was cooled to 0° C. and hypochlorous acid (40.0 g of 36.2% solution, 276 mmol) was added dropwise over 12 minutes. The resulting clear yellow solution was then stirred for 30 minutes at room temperature, the organic phase separated and dried (MgSO4) and the ethyl acetate removed in vacuo to give 39.35 g of low-melting solid product. the organic phase separated dried (MgSO4) the ethyl acetate removed in vacuo

Conditions: temp:1.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Ammonium hydroxide (250 ml) was stirred and cooled to 1° C. and 2,2-dimethyl valeroyl chloride (49.7 g, 95%, 318 mmol) was added dropwise over 30 minutes. After stirring at room temperature for an additional 1/2 hour, the white solid product was recovered by filtration, washed with water and allowed to air dry to give 35.4 g (86%) of the desired amide, mp 94°-95° (lit. mp 95°-96° C.). the white solid product was recovered by filtration washed with water to air dry

Conditions: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.
