Reaction Steps

The tile compound was prepared in analogy to the procedure described in Example 68 using 5-(4-chlorophenyl)-1-(8-methoxy-3-methyl-[1,2,4]triazolo[4,3-a]pyridin-6-yl)-4-propionylpyrrolidine-2,3-dione (Step 84.5) and (2-(2,2,2-trifluoroethoxy)ethyl)hydrazine hydrochloride in MeOH and TEA. The crude material was first purified by silica gel chromatography (hexane/EtOAc/MeOH 75:25:5 to 5:1) followed by preparative achiral SFC (Propyl-pyridyl-urea, gradient 13-18% in 6 min_total 11 min). tR: 1.04 min (LC-MS 2); ESI-MS: 549 [M+H]+ (LC-MS 2).
