  • 2-(2-Ethoxy)ethoxyethyl benzimidazolecarbamate
    Patent number: 4001423
    Abstract: Phytotherapeutic compositions comprising diethylene glycol ether solutions of 2-(2-ethoxy)ethoxyethyl benzimidazolecarbamate are prepared by: (a) heating and agitating an opaque, fluid suspension of methyl 1-(butylcarbamoyl)-2-benzimidazolecarbamate and dimethylsulfoxide until the fluid clarifies whereby the butylcarbamoyl group is removed from the carbamate; (b) adding methanol to the clarified fluid to precipitate a paste containing methyl 2-benzimidazolecarbamate and methanol; (c) separating the supernatant fluid from the paste; and (d) admixing diethyleneglycol monoethyl ether with the paste to form a fluid slurry and heating the slurry, with agitation, until it clarifies to thereby obtain a diethylene glycol monoethyl ether solution of 2-(2-ethoxy)ethoxyethyl benzimidazolecarbamate, and thereafter diluting the solution with diethylene glycol monoethyl ether to obtain suitable use concentrations of the carbamate.
