摘要： N-[1-(Chloromethyl)propyl]acetamide, for the synthesis of ethambutol hydrochloride, d,d'-2,2'-(ethylenediimino)-di-1-butanol dihydrochloride, is produced in high purity and good yields by the reaction of butene-1, a nitrile, preferably an excess of acetonitrile, and chlorine to form N-[1-(chloromethyl)propyl]acetimidoyl chloride which is hydrolyzed to N-[1-(chloromethyl)propyl]acetamide. This may be hydrolyzed further to dl-2-amino-1-butanol, which can be isolated as the hydrochloride, or free base, or a mixture, resolved with L(+)-tartaric acid and the d-2-amino-1-butanol reacted with ethylene dichloride and then hydrochloric acid to form ethambutol hydrochloride.

摘要： The present invention provides a flexible on-chip testing circuit and methodology for measuring I/O characterization of multiple I/O structures. The testing circuit includes a register bank, a central processing controller (CPC), a character slew module, a delay characterization module, and a character frequency module. The register bank stores multiple instructions, and measurement results. The CPC fetches the instructions from the register bank. The CPC includes various primary and secondary state machines for interpreting the fetched instructions for execution. Depending on the input instruction the CPC applies stimulus to the IUT and the output of the IUT is used by the Local characterization modules (CHARMODULE) to extract the desired characterization parameters such as the character slew module which measures a voltage rise/fall time either for a single voltage IUT or a multi-voltage IUT. The Test Methodology for STIOBISC consists of an automated ATE pattern generation from verification test benches and automated result processing by converting the ATE data logs into the final readable format, thereby considerably reducing the test setup and output processing time. The testing circuit can operate in multiple modes for selecting one of these modules.
