Versuchsvorschrift

(S)-4-(2-chloro-6,7-dihydro-5H-pyrrolo[3,4-d]pyrimidin-4-yl)-3-methylmorpholine hydrochloride (intermediate 6) (330 mg, 1.3 mmol), was dissolved in dry THF with srirring and treated with ethyl chloroformate (136 uL, 1.4 mmol) and NaHCO3 (218 mg, 2.6 mmol) at room temperature (20° C.) overnight. The mixture was concentrated in vacuo and the residue purified by flash chromatography using a mixture of 0-100% petrol ether/ethyl acetate as eluent, yielding the title compound (475 mg, 1.46 mmol, 41%).
