Abstract
NEW MATERIAL:A benzoxazine derivative shown by the formula I (R1 is alkyl or aryl; R2 is alkyl, or R1 and R2 are bonded to form alkylene; R3 is H, alkyl, alkoxy, etc.; R4 is H, alkyl, aryl; R5 is H, or alkyl; R6 is H, alkyl, etc.; R5 and R6 linked to the third position of pyridine ring form trimethylene containing oxo group).
EXAMPLE: 2,2-Dimethyl-3-(pyrido-2-ylmethyl)-4-oxo-4H-1,3-benzoxazine.
USE: An anti-inflammatory agent. The titled compound is hydrolyzed with an aqueous solution of a mineral acid to give a 2-aminomethylpyridine derivative, a raw material for drugs.
PROCESS: A compound shown by the formula II (X is halogen) is reacted with a compound shown by the formula III in one to twice the molar amount of the compound, to give a compound shown by the formula I.
