Participants

Conditions

Temperature: 130 °C

Procedure

80 mg (0.17 mmol) of 5-chloro-7-(2-chloro-4-fluorophenyl)-2-[1-(propan-2-yl)piperidin-4-yl][1,2,4]triazolo[1,5-c]pyrimidine hydrochloride, 64.9 mg (0.2 mmol) of 1-[2-amino-6-(piperidin-3-ylamino)pyridin-3-yl]-2,2,2-trifluoroethanone hydrochloride (Example 22A) and 0.17 ml (0.99 mmol) of N,N-diisopropylethylamine were initially charged in 1 ml of DMSO. The mixture was heated in the microwave at 130° C. for 30 min. This gave, after purification of the crude product by preparative HPLC (Method 11), 32 mg (28% of theory) of the product as a solid.
