Title: Novel aldehyde compound and its preparation
Inventor: KIKUCHI HARUHIKO
IPC: C07D321/12
Filed: 1981-04-03
Abstract: NEW MATERIAL:2-( 3-Benzylisopropylamino-2-hydroxypropoxy )-6-nitrophenylacetaldehyde.  
     USE: An intermediate for preparing 4-(3-isopropylamino-2-hydroxypropoxy)indole (hereinafter referred to as pindolol) useful as a medicine having the β-adrenergic blocking action.  
     PROCESS: A compound of formulaIis treated with an aqueous solution of an acid, e.g. HC1 or H 2 SO 4 , in the presence of an organic solvent to extract the resultant reaction mixture and give a crude oily product of formula II, which is then allowed to stand to deposit a crystalline solid. The resultant solid is separated, treated with an aqueous solution, neutralized with an acid and then extracted with a solvent to afford the aimed compound of formula III. In case the resultant compound of formula III is used as an intermediate in place of the compound of formula to carry out the two-stage hydrogenation reaction, the necessary amount of the catalyst is reduced and the pindolol is obtained in high yield without requiring the purification.

Filed: 1978-04-29
Abstract: PURPOSE: To protect a mirror-finished plate from damage by eliminating unnecessary grinding. This is accomplished by detecting foreign matters on the mirror- finished plate by means of a foreign matter detector, and by removing the foreign matters.  
     CONSTITUTION: A mirror-finished plate, having passed through a grinder 2, is transfered to the first foreign matter detector 4 and there, presence of foreign  matters on the plate is examined. If the plate has no foreign matter, it is transfered through a duct 3 to a build-up position 11, but if foreign matters are detected on the mirror-finished plate, the first foreign matter detector 4 memories their positions, then the plate is transfered by the first conveyor 7 to a by-path 5, where a foreign matter remover 6 receives the mirror-finished plate with foreign matters on it and removes the foreign matters whose positions have been memorized earlier. Finally, the presence of the foreign matter is reexamined by the second foreign matter detector 8 and if there is none on the plate, it is stored in a storage conveyor 9 so that the plate is transfered from the conveyor 9 to the build-up position 11 next time when foreign matters are detected on another plate.
