Reaction Conditions

Reaction Steps

N-(4-Methoxybenzyl)-5-[2-(methylthio)ethoxy]pyrimidin-2-amine (172.4 mg) was dissolved in trifluoroacetic acid (3 mL) at room temperature, and the solution was stirred at 60° C. for 2.5 hours. The reaction mixture was concentrated under reduced pressure, and the resulting residue was purified by preparative silica gel thin layer chromatography (chloroform:methanol=15:1) to obtain 5-[2-(methylthio)ethoxy]pyrimidin-2-amine (34 mg, 18% in 2 steps) as colorless amorphous solid.
