Abstract
NEW MATERIAL:An indazole derivative of formula I: (A is condensed pyridine or thiophene ring).
EXAMPLE: 3-Vinyl-pyridino[2,3,C]1H-pyrazole.
USE: Central nervous system depressants or their intermediates.
PROCESS: A 1,2-diazepine of formula II is subjected to irradiation with light or thermal reaction to give the compound of formula I. The compound of formula II can be obtained by irradiating an N-iminopyridine derivative of formula V with light, by reducing the resulting compound of formula III, and by dehydrogenating the reduced compound of formula IV.
