Methylmagnesium bromide (0.105 mL, 0.31 mmol) was added to an ice-cold solution of 1-(6-(((3,3-difluorocyclobutyl)methoxy)methyl)-2-(3-methoxy-4-(4-methyl-1H-imidazol-1-yl)-phenylamino)pyrimidin-4-yl)ethanone (16 mg, 0.03 mmol) in tetrahydrofuran (5 mL) under argon atmosphere. The mixture was stirred for 10 min. Methylmagnesium bromide (0.058 mL, 0.17 mmol) was added and the mixture was stirred for 10 minutes. The reaction was quenched with of ammonium chloride (aq, sat). The mixture was concentrated. The residue was extracted with dichloromethane. The organic phase was dried over sodium sulfate and concentrated. The residue was purified by preparative HPLC to give the title compound as a dry film (4 mg, 24%).
