| 摘要 |
<p>This invention provides advantageous processes for preparing quinazolinones of Formula (I) wherein: R1 is C1-C10 alkyl; C3-C10 alkenyl; C3-C10 cycloalkyl; C3-C10 halocycloalkyl; C4-C10 cycloalkylalkyl; C4-C10 halocycloalkylalkyl; or C3-C10 alkynyl; R2 is C1-C10 alkyl; C3-C10 alkenyl; C3-C10 cycloalkyl; C3-C10 halocycloalkyl; C4-C10 cycloalkylalkyl; C4-C10 halocycloalkylalkyl; C4-C10 cycloalkyl; C4-C10 halocycloalkyl; or C3-C10 alkynyl; and R?3 and R4¿ are each independently hydrogen or halogen; from compounds containing the moiety (IIg). This invention further provides certain compounds of Formula (II), (IIIa), or (IVa) where R7 is C2-C6 alkyl.</p> |
