Method of producing quinazolinone derivatives |
| abstract |
FIELD: chemistry. n SUBSTANCE: invention relates to an improved method of producing quinazoline derivatives of structural formula I: n , n where values of radicals R 1 -R 6 , R 8 , W, P are given in the claim. The method involves reacting an aldehyde of formula II: n n n n with ethylene carbonate to form a compound of formula III: n n n n and reacting a compound of formula III with a compound of formula IV: n n n n to form a compound of formula I. The invention also relates to methods of producing derivatives of the compound of formula I of structural formulae VI and VIII. n EFFECT: said methods enable to obtain products with low content of impurities and high output. n 23 cl, 7 ex |
