Abstract

NEW MATERIAL:A spiro compound of formula I (R1 is H or lower alkyl; R2 is lower alkyl; R3 is esterified carboxy).
EXAMPLE: 1, 5-Dimethyl-3-oxo-4-ethoxycarbonyl-4-pyrroline-2-spiro-4'-( 1'-isonicotinoyl-1',4'-dihydropyridine).
USE: Medicine having antispasmodic and sedative activities.
PROCESS: The compound of formula I is prepared by reacting 1mol of a compound of formula II with >1mol, pref. about 4mol of a reactive derivative of isonicotinic acid of formula III (e.g. acid chloride, acid bromide, active ester, etc.) in a solvent such as methylene chloride, benzene, etc., under heating.
