1. A process for manufacturing 4-substituted amino-benzoxazinones of formula (I), wherein R1 is H or halogen; R2 is halogen; R3 is H or halogen; R4 is C1-C6-alkyl, C1-C6-haloalkyl, C3-C6-cycloalkyl, C3-C6-alkenyl, C3-C6-haloalkenyl, C3-C6-alkynyl, C3-C6-haloalkynyl, C1-C6-alkoxy or C3-C6-cycloalkyl-C1-C6-alkyl; and W is O or S;whereina NH-benzoxazinone of formula (II), or a salt thereof, wherein R1, R2, R3 and W are defined as in formula (I);is reacted with a compound of formula (III),
R4-L (III) wherein R4 is defined as in formula (I); L is halogen or OS(O)2R7; and R7 is C1-C6-alkyl, C1-C6-haloalkyl, C1-C6-nitroalkyl, C1-C6-alkoxy-C1-C6-alkyl, C3-C6-cycloalkyl, phenyl or phenyl-C1-C6-alkyl, wherein each phenyl ring independently of one another is unsubstituted or substituted by 1 to 5 substituents selected from the group consisting of halogen, CN, NO2, C1-C6-alkyl, C1-C6-haloalkyl or C1-C6-alkoxy; in the presence of a base. |
