N-(4-amino-2,6-dichlorophenyl)acetamide

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

Procedure: A mixture of 20 parts of N-(4-amino-2,6-dichlorophenyl)acetamide, 10 parts of 2-propanone, 2 parts of a solution of thiophene in methanol 4%, 400 parts of methanol, 5 parts of potassium fluoride and 18 parts of 2-propanol, saturated with hydrogen chloride was hydrogenated in a Parr apparatus and at 50° C. with 2 parts of platinum-on-charcoal catalyst 5%. After the calculated amount of hydrogen was taken up, the catalyst was filtered off and the filtrate was evaporated. The residue was crystallized from acetonitrile. The product was filtered off and dried, yielding 15.7 parts (66.7%) of N-[2,6-dichloro-4-[(1-methylethyl)amino]phenyl]acetamide (int. 98). the catalyst was filtered off the filtrate was evaporated The residue was crystallized from acetonitrile The product was filtered off dried

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