Hydrochloric Acid → 2-Chloro-5-(pyrimidin-2-ylamino)phenol

Participants

Reaction Steps

2-Chloropyrimidine (1.5 g, 13.3 mmol), 5-amino-2-chlorophenol (318 mg, 2.2 mmol) and 37% HCl solution (1.1 mL, 13.3 mmol) in 10% aqueous EtOH solution (10 mL) was stirred at 90° C. for 24 h. Afterwards, 2-chloropyrimidine (1.5 g, 13.3) was added and after 24 h, the reaction mixture was diluted with AcOEt and washed with 5% aqueous K2CO3 solution and brine. The organic phase was dried over Na2SO4, concentrated and the crude product (179 mg, 36% yield) was used for the next step without additional purification.
