The synthesis of [4a‐13C]‐6‐methyltetrahydropterin, a synthetic cofactor for phenylalanine hydroxylase, is described. [2‐13C]‐ethyl bromoacetate was converted in four steps to [5‐13C]‐2,4‐diamino‐6‐hydroxypyrimidine in 86% yield. The latter was nitrosated, reduced, condensed with pyruvic aldehyde, and reduced to afford pure [4a‐13C]‐6‐methyltetrahydropterin in a net overall yield of 16%.
