Patent number: 6897309Abstract: This invention describes a process for preparing hydroxyazapirones of Formula I from azapirones of Formula II. The process comprises treating azapirones with a strong base, monitoring enolate formation of the azapirone by IR spectroscopy, and reacting the enolate with a source of molecular oxygen in the presence of a reductant. The process is suitable for large scale production of hydroxyazapirones.Type: GrantFiled: August 7, 2003Date of Patent: May 24, 2005Assignee: Bristol-Myers Squibb CompanyInventors: Jeffrey Depue, Atul S. Kotnis, Simon Leung, Eric D. Dowdy, Daniel J. Watson

Publication number: 20030141589Abstract: An apparatus for processing a high-frequency electrical signal. The apparatus comprises a circuit carrier and an electrical circuit mounted on the circuit carrier. The electrical circuit processes a signal within a predetermined frequency range, the predetermined fundamental frequency range having a low end in the range being about 1 GHz or higher. An encapsulent material encapsulates at least a portion of the electrical circuit. The circuit carrier, electrical circuit, and encapsulent material form a package having resonant frequencies. The resonant frequencies are outside the predetermined frequency range.Type: ApplicationFiled: January 22, 2003Publication date: July 31, 2003Applicant: HEI, Inc.Inventors: Simon Leung, Guanghua Huang
