Hydrochloric Acid → 2-Chloro-5-iodo-4-(pyrrolidin-1-yl)pyrimidine

Participants

Reaction Steps

To a solution of 2,4-dichloro-5-iodopyrimidine (5.00 g) synthesized according to the method described in WO2008/155140 A1 in tetrahydrofuran (50 mL), N,N-diisopropylethylamine (3.49 mL) and pyrrolidine (1.65 mL) were added under ice cooling, and the mixture was stirred at the same temperature for 3 hours. To the reaction mixture, 1.0 mol/L aqueous hydrochloric acid was added. The solid matter was taken by filtration, washed with water, and then dried under reduced pressure to obtain 2-chloro-5-iodo-4-(pyrrolidin-1-yl)pyrimidine (H1, 4.49 g).
