    Abstract: A new synthetic route is described that leads to TRH in excellent yield; it uses a new precursor, benzyloxycarbonyl-L(O5-methyl)glutamyl-L-histidyl-L-prolinamide. This substance can be made in a three-step process providing good yields. The new precursor can be converted to TRH by simple hydrogenolysis and cyclization. These two steps can be run without isolation of the intermediate L-(O5-methyl)glutamyl-L-histidyl-L-prolinamide.
