Procedure
By replacing the p-methylphenylglycine employed in Procedure 14, Step A by an equivalent quantity of cyclopentylglycine, there is obtained cyclopentylglycinamide. Substituting this cyclopentylglycinamide for that employed in Procedure 13 and following the methods described in Steps A and B of Procedure 13, there is obtained in Step A 2-hydroxy-3-cyclopentylpyrazine and in Step B 2-chloro-3-cyclopentylpyrazine.
