Reaction Steps

3-(6-Amino-1-methyl-1H-pyrazolo[3,4-d]pyrimidin-3-yl)-4-methoxy-benzaldehyde (Example 75) (0.040 g, 0.141 mmol) is suspended in dry MeOH (2.5 ml) and THF (1 ml). The reaction mixture is cooled to 0-5° C. (ice-bath) and sodium borohydride (0.006 g, 0.1551 mmol) is cautiously added. The reaction mixture is stirred at room temperature for 24 hours, filtered, washing with MeOH and concentrated in vacuo. The resulting solid is triturated in MeOH (minimal) and collected by filtration to afford the title compound as an off-white solid.
