Improved synthesis of Watasenia preluciferin

On heating a mixture of 2-amino-3-benzyl-5-(p-hydroxyphenyl)pyrazine (2) and a large excess of p-hydroxyphenylpyruvic acid (4) at 130-140 °C in dioxane, without any reductive treatment, Watasenia preluciferin (1) was obtained directly in one batch process in 63% yield.
