Efficient synthesis of N-methylamides and amines via 4-(alkylamino)benzyl- N-methylamine as a new protecting group
4-(Alkylamino)benzyl-N-methylamine is a good protecting group for the synthesis of N-methylamides and amines. The N-debenzylation of N-methylamides and amines can be carried out selectively and efficiently under condition using trifluoroacetic acid (TFA).
