Reaction Steps

A microwave vial containing 5-methylsulfanyl-[1,2,4]triazolo[1,5-a]pyridin-2-ylamine (13.5 g, 74.9 mmol), 1-(2-(4-bromophenoxy)ethyl)pyrrolidine (20.2 mL, 97.3 mmol), tris(dibenzylideneacetone)dipalladium (3.42 g, 3.74 mmol), xantphos (4.33 g, 7.49 mmol), sodium tert-butoxide (14.7 g, 150 mmol) and 1,4-dioxane (90 mL) was heated under microwave radiation (150° C., 10 min). N,N-Dimethylacetamide (1 mL) was added to assist with microwave absorption. The volatiles were removed under rotary evaporation and the product then purified by graduated flash column chromatography (2-10% methanol: dichloromethane) to provide a pale brown solid. Yield: 19.3 g, 70%; LCMS method: 2, RT: 2.28 min, MI: 370 [M+1]. 1H NMR (CDCl3, 300 MHz): 7.53 (d, 2H), 7.40 (d 1H), 7.26 (d, 1H), 7.10 (s, 1H), 6.93 (d 2H), 6.64 (d, 1H), 4.11 (t, 2H), 2.90 (t, 2H), 2.64 (s, 7H), 1.81 (s, 4H).
