Reaction Conditions

Temperature	130 °C

Reaction Steps

50 mg (0.155 mmol) of the amine (Example 8A) are introduced into 3 ml of dry DMSO, 51.2 mg (0.31 mmol) of 2-fluoro-5-(trifluoromethyl)pyridine and 31.1 mg (0.31 mmol) of potassium bicarbonate are added, and the mixture is heated at 130° C. under argon for 16 h. Purification by preparative HPLC results in 22 mg (30% of theory) of the product as a solid.
