実験手順

A solution of 2,4-dichloropyrimidine (2.0 g) in EtOH (25 mL) was cooled to 0-20° C. and treated with hydrazine (2.8 mL). The progress of the reaction was followed by TLC using 10% MeOH:CH2Cl2 as mobile phase and visualizing under UV light. The mixture was concentrated under reduced pressure to afford 3.1 g of crude 2-chloro-4-hydrazinyl-pyrimidine (yield=94.8%).
