HCID 205675442-(2-Hydroxyethoxymethyl)pyrazine

Procedure

2-Chloromethylpyrazine is reacted with the sodium salt of ethylene glycol to give 2-(2-hydroxyethoxymethyl)pyrazine which is treated with thionyl chloride to give 2(2-chloroethoxymethyl)pyrazine. Using this intermediate in place of 4-(3-chloropropoxy)methylimidazole in the procedure of Example 22 gives the title compound.
