Title: Method for preparing of 6- n- exophenylcarbamoyl- 3- (beta- phenylisopropyl) sidnonimine
Inventor: DRANDAROV KONSTANTIN B
IPC: C07D271/04
Filed: 1989-07-27
Abstract: This compound is used for medical purposes as a biologically active substance with a stimulating effect on the nervous system and is commonly known under the generic name of mesocarb. The method uses a simplified flow diagram, which ensures increased yield rates in terms of final product. The method involves carrying out a cyan-methylation of β-phenyl-iso-propylamine, followed by a nitrosification in an acetic acid medium in the presence of catalytic amounts of potassium bromide and subjecting the product to an intramolecular cyclization until 3-/ β-phenyl isopropyl/ sydnonimine is obtained.The latter is settled using an aqueous solution of nitrate ions, the nitrate obtained made to react with phenyl isocyanate in a chloroform medium in the presence of triethyl amine.

Abstract: ABSTRACT OF THE DISCLOSURE    Rear view mirrors for modern aerodynamic streamlined automobiles are mounted on the sides of the vehicle body as close to the front end as possible without interfering with components of the vehicle to extend above and laterally outward from the hood to reflect approaching vehicles on both sides of the automobile and provide clear vision to the driver as the vehicles approach and pass the rear end of the automobile.  The positioning of the mirrors forwardly from the driver's eyes at the greatest distance permitted by the vehicle without forming an obstacle reduces the angle of incidence and the angle of reflection to a minimum thereby avoiding heretofore encountered blind spots in the driver's rear view vision.  The mirror mounting can be streamlined into the front sides of the vehicle body in original equipment vehicles or can be provided as an accessory.   The added accessory mountings  include  a  streamlined  cup-like  base carrying initial temporary attachments such as suction cups or magnets and have a deformable gasket around the periphery thereof to be pressed tightly against and follow the contour of the vehicle's side wall.
