実験手順

A solution of 4-methyl-1H-imidazole (1.98 g, 24.11 mmol) in N-methylpyrrolidinone (NMP) (18 mL) is added to a solution of sodium hydride (0.82 g, 60%, 20.5 mmol) in NMP (18 mL) at 20-25° C. under an atmosphere of nitrogen. The mixture is stirred for 1 hour, before a solution of 3-fluoro-5-trifluoromethyl benzonitrile (XXI) (3.2 g, 16.4 mmol) in NMP (8 mL) is added. The reaction mixture is stirred for 2 hours at 20-25° C. and then water (120 mL) is added within 20 minutes and the resulting suspension is stirred for 16 hours.
