Definitions
- Met stands for an alkali metal, preferably lithium, sodium or potassium, in particular lithium, and
- R ' is C-
- R 1 has the meanings given in claims 1 to 4; optionally in the form of the corresponding sodium or potassium phenates, under basic reaction conditions, preferably in a polar organic solvent.
- the amount of the alkali metal hexaalkyldisilazane used is determined by the amount of the nitrile of the formula (II) used. At least 1 mol, preferably 1.01 to 1.15 mol, of alkali metal hexaalkyldisilazane are used per mol of nitrile of the formula (II). The amount of 5 ethereal solvent used is between 0.7 and 1.5, preferably 0.9 to 1.3 kg per mol of compound of the formula (II) used.
- the aqueous lower phase is separated off and an organic solvent selected from the group consisting of acetone, methyl isobutyl ketone and methyl ethyl ketone, optionally also a mixture of two of the abovementioned solvents, particularly preferably a mixture of acetone, is added to the organic phase and methyl isobutyl ketone in a ratio of 3-1: 1, particularly preferably in a ratio of 2.5-1, 5: 1.
- the crystallization of the compounds of the formula (IVA) is initiated by adding aqueous hydrochloric acid. About 1 to 1.2 moles of acid, preferably hydrochloric acid, are used per mole of compound of formula (II) originally used. According to the invention, the addition of preferably 32-37%, particularly preferably 37% hydrochloric acid is preferred.
- the compounds of the formula (IVA) are extracted from the by conventional methods, for example by centrifugation
- Chlorinated hydrocarbons such as methylene chloride or, according to the invention, aromatic hydrocarbons such as benzene, toluene, xylene, preferably toluene, can be used as the non-polar organic solvent.
- aromatic hydrocarbons such as benzene, toluene, xylene, preferably toluene
- the compounds of the formulas (V) and (VI) are used in an approximately stoichiometric ratio, if appropriate one of the two reactants can also be used in a slight excess (for example 15%).
- the amount of solvent to be used depends on the amount of starting material used. Between 1 and 2 liters of water and between 0.3 and 1.0 liters of the organic solvent, preferably between 1.5 and 1.8 liters of water and 0.5 to 0.7 liters, are used per mole of compound of formula (VI) of the organic solvent used.
- Example 6 ([4- (3- (4-H - (4-Hvdroxy-phenyl) -1 -methyl-ethyl-phenoxymethyl) - benzyloxy) -phenvn-imino-methyl) -carbamic acid ethyl ester hydrochloride in a solution of 45 , 5 kg (272 mol) of lithium bis (trimethylsilyl) amide in 266 kg of THF become 132 kg (247 mol) of 4- (3- ⁇ 4- [1- (4-tetrahydropyranyl-phenyl) -1-methyl-ethyl] - Phenoxymethyl ⁇ -benzyloxy) -benzonitrile (Example 5) metered in at about 0 ° C.
