Reaction Steps

In 30 ml of t-butyl methyl ether was suspended 897 mg of sodium amide in a nitrogen stream, and 2.13 g of 2-pyrrolidinone was slowly added thereto dropwise, followed by refluxing for 2 hours. After allowing to cool, 1.97 g of 2-chloro-N-(2,6-dimethylphenyl)acetamide was added thereto, followed by refluxing for 2 hours. To the reaction mixture was added 50 ml of hot water of about 70° to 85° C., and the mixture was allowed to cool with stirring. The thus formed crystals in the aqueous layer were collected by filtration and dried under reduced pressure to obtain 2.19 g (89%) of the titled compound.
