Abstract
The new synthesis strategy for the preparation of secondary amines starts from N-alkyl- phthalimides which are reduced to the corresponding o-hydroxymethyl-N-alkyl-benzamides. After protection of the hydroxy group as tetrahydropyranyl ether the N-alkyl-benzamides are alkylated to o-(tetrahydropyranyloxymethyl)-N, N-dialkyl-benzamides. The deprotection of the hydroxy group and the release of the secondary amines can be achieved in excellent ...
