Procedure

A suspension of 5-(benzyloxy)-2-methylpyrazolo[1,5-a]pyridine-3-carbothioamide (820 mg, 2.8 mmol) obtained in Example 30-B(vi) and ethyl 2-chloro-3-(2-fluorophenyl)-3-oxopropanoate (3.1 g, 13 mmol) obtained in Example 22-B(i) in 2-propanol (50 mL) was stirred at 90° C. for 7 h. The reaction mixture was allowed to cool to room temperature, and the precipitated solid was collected by filtration. The solid was washed with EtOAc and diisopropyl ether, and dried to give the title compound (1.0 g, 75%) as a yellow solid.
