Paragraph 0012; 0013; 0014; 0015; 0016, (2017/07/21)
The invention discloses a method for preparing N-methyl-N-phenylacetamide acetate by a one-pot method. The method comprises the following steps of (1) under a solvent-free state, dripping N-methylaniline into chloroacetyl chloride, heating to react after dripping is finished, removing hydrogen chloride, and cooling, so as to obtain N-methyl-N-phenylacetamide; (2) under the solvent-free state, directly adding acetic acid and a catalyst into the N-methyl-N-phenylacetamide obtained in the previous step, heating to react, removing the hydrogen chloride, preserving heat until the reaction is finished, and filtering, so as to obtain the N-methyl-N-phenylacetamide acetate, wherein the catalyst is a mixed catalyst of organic alkaline and quaternary ammonium salt. The preparation method has the advantages that a solvent is not used, the water washing is not needed, the green and environment-friendly effects are realized, only one reaction kettle is needed, and the cost is low.

The reaction of thiols with glyoxamides provides a convenient method for the generation of thionium ions and the initiation of Pummerer-type reactions. When the glyoxamides contain tethered aromatic nucleophiles, N-heterocycles are formed by a thionium ion cyclisation. The scope and mechanism of the connective Pummerer-type process has been investigated using a range of thiols, Lewis acids and both mono- and bis-glyoxamides. The utility of the process has been illustrated in a synthesis of the indoloquinoline natural product, neocryptolepine. The Royal Society of Chemistry 2009.

Therapeutic as well as preventive measures to alleviate the symptoms of dermatologic and other conditions and disorders with phenyl alpha-acyloxyacetamide derivatives is disclosed. Dermatologic and other conditions and disorders in humans in which the compounds may be useful include pruritus, atopic dermatitis, eczema, psoriasis, acne, dry skin, dandruff, malodors of integumental areas; and various aches, pains and discomforts of skin, joints and other body parts. The phenyl alpha-acyloxyacetamide derivatives include, for example, N-ethyl phenyl alpha-acetoxyacetamide, N-benzyl phenyl-alpha-acetoxyacetamide, N-phenethyl phenyl-alpha-acetoxyacetamide, N-benzyl diphenyl-alpha-acetoxyacetamide and N-phenethyl diphenyl-alpha-acetoxyacetamide. The compositions containing the active ingredients are also useful for treatment of skin conditions or disorders, and musculoskeletal disorders, of domestic animals, for example dogs, such as dry skin, scurf, eczema, mange, prurigo, malodors, arthritis or myositis. Some phenyl-alpha-acyloxyacetamide derivatives may have a tranquilizing effect.
