Participants

Reaction Steps

1-(4-Amino-9-propyl-pyrido[3′,2′:4,5]thieno[3,2-d]pyrimidin-7-yl)-piperidin-4-one (Example 4) (341 mg, 1.00 mmol) and (S)-2-amino-1-phenylethanol (142 mg, 1.00 mmol) was dissolved in 10 mL of dry DMF. MP-Cyanoborohydride (0534 mg, 1.20 mmol) was added followed by 10 drops of glacial acetic acid. This mixture was shaken for 16 h. The resin was removed by filtration and washed with MeOH and dichloromethane. The filtrate was evaporated. The residue was treated with 2 M sodium carbonate solution. The resulting solid was collected by filtration and recrystalized from MeOH/acetonitrile to give the title compound as a pale-colored solid (0.260 g, 56%).
