Reaction Conditions

Reaction Steps

Combine 6-chloro-2-methylpyrimidin-4-amine (708 g, 4.93 mol) and MeOH (7.08 L) in a 20 L round bottom flask equipped with a mechanical stirrer. Cool to 0-5° C. Add iodine monochloride (4.806 kg, 29.6 mol) dissolved in MeOH (6 L) using an addition funnel over a period of 1 h. Warm the reaction mixture to RT and stir at RT for 16 h. Cool the reaction mixture to 0-5° C. and add sodium sulfite (46 L, 20% aqueous solution). Filter the resulting solid and wash with water (2 L) followed by hexane (3 L). Dry the solid under vacuum to afford the title compound as a white solid (1061 g, 80%). LC-ES/MS m/z 269.9 (M+1).
