Procedure
To a stirring solution of (S)-4-(2-chloro-6,7-dihydro-5H-pyrrolo[3,4-d]pyrimidin-4-yl)-3-methylmorpholine hydrochloride (intermediate 6) (870 mg, 3.01 mmol) in dichloroethane, was added cyclopropanecarboxaldehyde (450 uL, 6.02 mmol) and Et3N (840 uL, 6.02 mmol). The reaction mixture was stirred at room temperature (20° C.) for 45 minutes, before adding sodium triacetoxy borohydride (1.28 g, 6.02 mmol). The reaction mixture was then stirred for a further 2 h at room temperature (20° C.) before partitioning between saturated NaHCO3 solution and DCM. The organic layer was recovered, dried over MgSO4, filtered and the solvent removed in vacuo, affording the title compound as a colourless oil (882 mg, 92% yield).
