    Abstract: The production of quaternary glycine nitriles (I) in which R1 and R2 may be the same or different and are an aliphatic, cycloaliphatic or araliphatic radical with 1 to 30 C atoms, whereby R1 and R2 may also form a saturated or unsaturated five or six-member heterocyclic ring together with the N atom to which they are bonded, which can also contain further hetero-atoms, be benzanellated and have alkyl side groups, while R2 may also be hydrogen; R3 is C1 to C4 alkyl or benzyl; R4 is hydrogen, C1 to C20 alkyl which may be interrupted by one or more non adjacent oxygen atoms, or a radical (a) in which R5 is a chemical bond or a C1 to C6 alkylene bridge and XO is a counterion; by the reaction of amines (II) in which the variables R1 and R2 have the above meanings, with a monoaldehyde (IIIa) R6-CHO or a dialdehyde (IIIb) OHC-R5-CHO in which R5 has the above meaning and R6 is hydrogen or C1 to C20 alkyl and hydrocyanic acid or an alkaline metal cyanide in an aqueous medium, followed by quaternation with an alkylation agent (IV) R3-X in which R3 has the above meaning and X is an initial group, by reacting the amines (II) with the aldehydes (III) and hydrocyanic acid or alkaline metal cyanide and quaternising in succession without isolating an intermediate product in an aqueous medium.

    IPC: C07D265/22

    Abstract: A process for the manufacture of 4H-3,1-benzoxazin4-ones of the general formula I in which R denotes hydrogen, C1-C4 alkyl, C1-C4 alkoxy, carboxyl, sulfo, nitro, or halogen, R denotes C1-C20 alkyl, phenyl, or phenylalkyl having from 1 to 4 carbon atoms in the alkyl group, in which a phenyl nucleus, if present, can be substituted by up to two C1-C4 alkyl groups, C1-C3 haloalkyl groups, C1-C4 alkoxy groups, C1-C3 haloalkoxy groups, C1-C4 alkylmercapto groups, C1-C3 haloalkylmercapto groups, carboxyl groups, sulfo groups, C1-C4 alkylsulfonyl groups, C1-C3 haloalkylsulfonyl groups, nitro groups, or halogen atoms and n is equal to 1 or 2, by the reaction of anthranilic acid or an anthranilic acid derivative of the general formula II with an acyl halide of the general formula III in which X denotes chlorine or bromine and R , R and n are as defined above, wherein the anthranilic acid II is reacted with an approximately stoichiometric amount of the acyl halide III, without the addition of a base, in an organic solvent at a temperature of from 60 DEG to 200 DEG C, after which the N-acyl anthranilic acid formed as intermediate is cyclized in known manner in situ.
