PROCEDURE

实验过程

A suspension of thiourea (620 mg) and 3-bromomethyl-pyrazine-2-carboxylic acid ethyl ester (2 g) in tetrahydrofuran was heated in the microwave at 120° C. for 5 minutes. The product formed an oil so the tetrahydrofuran was simply decanted to leave 3-carbamimidoylsulfanylmethyl-pyrazine-2-carboxylic acid ethyl ester hydrobromide (2.2 g) as an oil. MH+=241, RT=0.26 min (Method A).
