Reaction Steps

Potassium carbonate (1.61 g, 11.6 mmol) and DMAP (0.18 g, 1.45 mmol) were added to a solution of methyl 3-methyl-1H-indole-6-carboxylate (1.1 g, 5.81 mmol) and 2-chloro-5-(2-fluorophenyl)-pyrimidine (1.21 g, 5.81 mmol) in dry DMSO (10 mL). The solution was stirred at 100° C. for 1 h, then cooled to room temperature and slowly poured into vigorously stirred water (100 mL). The precipitating solid was filtered off, washed with water and dried in vacuum. Light-brown solid. Yield: 1.89 g (80% chemical purity). HPLC-MS: m/z [M+H]+=362.
