Participants

Reaction Steps

To a cooled (0° C.) suspension of N-(2-methyl-4-(1-methyl-1H-pyrazol-4-yl)phenyl)formamide (Preparation 99, 40 mg, 0.186 mmol) in THF (4 mL) was added NaH (60% dispersion in oil, 12 mg, 0.297 mmol). The reaction mixture was stirred at room temperature for 10 minutes. The reaction mixture was cooled to 0° C. and 8-chloro-2-(methylsulfonyl)pyrido[3,4-d]pyrimidine (Preparation 97, 59 mg, 0.242 mmol) was added. The reaction mixture was stirred for 18 hours, whilst slowly warming to room temperature. The reaction mixture was concentrated in vacuo. The residue was partitioned between EtOAc (30 mL) and water (30 mL). The aqueous layer was extracted with EtOAc (30 mL) and DCM (30 mL). The combined organic layers were washed with water (30 mL) and brine (30 mL), dried (MgSO4) and concentrated in vacuo. The residue was purified by silica gel column chromatography eluting with 0-5% MeOH in EtOAc to give the title compound (79 mg, 97%).
