A convenient route is established for the preparation of N α-Fmoc-N ε-(Boc, methyl)-l-lysine and N α-Fmoc-N ε-dimethyl-l-lysine as building blocks to be used for the synthesis of methylated peptides. This methodology is based on the use of malonate derivatives and dibromobutane to produce key intermediates, l-2-amino-6-bromohexanoic acid derivatives, which could be modified to the required group at
