N-[(4-benzylmorpholin-2-yl)methyl]-7-[[(7R)-8-cyclopentyl-7-ethyl-5-methyl-6-oxo-7H-pteridin-2-yl]amino]-2,3-dihydrobenzofuran-4-carboxamide 2e (0.19 g, 0.30 mmol) was dissolved in 30 mL of methanol followed by the addition of palladium/carbon (40 mg, 10%), filled with hydrogen two times. The reaction solution was stirred for 2 hours and filtered. The filtrate was concentrated under reduced pressure to obtain the crude title compound 7-[[(7R)-8-cyclopentyl-7-ethyl-5-methyl-6-oxo-7H-pteridin-2-yl]amino]-N-(morpholin-2-ylmethyl)-2,3-dihydrobenzofuran-4-carboxamide 2f (163 mg) as a white solid, which was used in the next step without further furification.
