摘要:
A process for preparation of 2-(10,11-dihydro-10-oxodibenzo[b,f]thiepin-2-yl)propionic acid (i.e., Zaltoprofen) is performed by subjecting 2-(4-amino-3-carboxy-methylphenyl)propionic acid or its salt to diazotization and subsequent reaction with thiophenol to produce 2-(3-carboxymethyl-4-phenylthiophenyl)propionic acid or its salt, and subjecting the product to cyclization reaction. Other related processes and related compounds are also disclosed.
摘要:
A semiconductor device socket prevents adhesion of foreign material to mounting surfaces of external leads of a semiconductor device. A positioning base of the socket supports external leads of the semiconductor device such that the lead ends of the leads do not contact a body of the socket. Movable contact terminals of the socket disposed opposite the external leads can move into and out of contact with the external leads.
