Procedure
A mixture of 5-(2,4-Diamino-pyrimidin-5-yloxy)-4-isopropyl-2-methoxy-benzamide (0.25 g, 0.79 mmol, prepared according to the procedure of Example 52) and Lawesson's reagent (0.96 g, 2.37 mmol) in anhydrous THF (20 ml) was stirred at room temperature for 16 hrs and concentrated in vacuo. Flash chromatography on silica (5% CH3OH in methylene chloride with 1% NH4OH) gave 5-(2,4-Diamino-pyrimidin-5-yloxy)-4-isopropyl-2-methoxy-thiobenzamide (0.201 g, 76% ) as a yellow solid.
