Procedure
In a flask was added 6-chloro-5-methoxypyrimidin-4-amine (500 mg, 3.13 mmol) and pyrrolidine (0.523 ml, 6.27 mmol) in toluene (5 ml). The reaction was heated to 80 C for 16 hours and then cooled to room temperature. The reaction was then concentrated to a white solid to give 5-methoxy-6-(pyrrolidin-1-yl)pyrimidin-4-amine (514 mg, 84% yield). LC/MS R.T.=1.25 mins (M+H=195.2).
