Reaction Steps

60 mg (0.26 mmol) of 2-chloro-6-(4-fluorophenyl)pyridine-3-carbonitrile, 77 mg (0.31 mmol) of 6-(piperidin-3-ylamino)pyridine-3-carbonitrile hydrochloride (Example 10A) and 0.225 ml (1.29 mmol) of N,N-diisopropylethylamine were initially charged in 2 ml of DMSO. The mixture was heated at 120° C. in a microwave for 30 min. The crude product was purified by means of preparative HPLC (method 13). 99 mg (50% of theory) of the product were obtained in solid form.
