Abstract
The method for the production of penicillin claimed in Specification 613,488 is modified by replacing the phenylacetyl hydrolysate or a salt thereof of the culture medium by a compound having the formula <FORM:0613491/IV(b)/1> wherein R, R1, R2 each represent either hydrogen methyl or ethyl radicles. These compounds may be manufactured either by refluxing the appropriate primary amine with phenylacetyl chloride or methyl phenylacetate, or by reacting the appropriate chloride or bromide with phenylacetamide in dioxane in the presence of potassium. The crude product is recrystallised from aqueous ethyl alcohol and then from benzene or a mixture of benzene with petroleum ether. Specified compounds are the N-crotyl-, N-allyl-, N-(3-ethyl allyl)-, N-(2,3-dimethylallyl)- and N-(3,3-dimethylallyl)-derivatives of phenyl acetamide. Specification 586,930, [Group VI], is referred to.
