Reaction Steps

N-Benzyl-2-chloro-7-ethynylthieno[3,2-d]pyrimidin-4-amine (30 mg, 0.096 mmol) was dissolved in anhydrous dioxane (0.5 mL) and (S)-1-aminopropan-2-ol (23 μL, 0.288 mmol) was added. The reaction mixture was stirred at 120° C. for 24 hours. After adding ethyl acetate (3 mL), the reaction mixture was washed with brine. After drying with MgSO4 and concentrating by filtration, purification by silica gel chromatography (ethyl acetate/hexane:1/3→1/1) yielded the target compound of Example 44 (17 mg, 50% yield).
