Reaction Steps

To a solution of (3S)-3-[(2-chloro-5-fluoro-pyrimidin-4-yl)amino]cyclohexanone (1.83 g, 7.49 mmol) in THF (100 mL) was added methylmagnesium bromide (21.4 ml of 1.4M solution, 29.96 mmol) at room temperature. The reaction mixture was stirred at room temperature for 5 minutes. To the reaction mixture was added aqueous saturated NH4Cl solution and EtOAc. The organic phase was washed with brine and dried with MgSO4, filtered and concentrated in vacuo. The two spots were separated by silica gel chromatography (120g silica gel column).
