Procedure
To (S)-1-ethyl-3-(2-fluoro-4-(4-(3-methylmorpholino)-6,7-dihydro-5H-pyrrolo[3,4-d]pyrimidin-2-yl)phenyl)urea (intermediate 18) (100 mg, 0.23 mmol) and triethylamine (64 μL, 0.46 mmol) in dry THF (3 ml) was added 1-acetylpiperidin-4-one (56 μL, 0.46 mmol) and stirred at room temperature for 30 min. To this sodium triacetoxyborohydride (97 mg, 0.46 mmol) was added. The reaction mixture was stirred at room temperature until analysis by LCMS indicated reaction was complete. The solvent was then removed in vacuo. Crude reaction mixture then was partitioned between ethyl acetate and water. The organic layer was recovered, dried with sodium sulphate and solvent removed in vacuo. Residue was then purified by prep HPLC (low pH) to afford a white solid (6.7 mg, 0.013 mmol, 6%).
