Process for the preparation of N-(hydroxyalkyl)-carbamid acid alkyl esters |
| abstract |
It has been found that alkyl (N- (hydroxyalkyl) carbamates of the formula (I) in which R¹ stands for alkyl and R² to R⁸ are identical or different and stand for hydrogen or for alkyl or R² and R³ together with the atoms to which they are attached form an optionally alkyl-substituted monocyclic ring and n denotes 0 or 1, can be obtained in high purity and very good space-time yields if amino alcohols of the formula (II) in which R² to R⁸ and n have the meaning given above, with chloroformic acid esters of the formula (III) in which R¹ has the meaning given above in the presence of aqueous alkali metal hydroxide solutions and optionally in the presence of an organic solvent at temperatures between 30 ° C and 110 ° C.n n n The substances produced according to the invention can be used as active substances in agents for repelling insects and mites (cf. EP-A 289 842). |
