Pyridine, 4-(4,5-dimethyl-4H-1,2,4-triazol-3-yl)- → 4-(5-{2-[5-(3-Chloro-phenyl)-[1,2,4]oxadiazol-3-yl]-propyl}-4-methyl-4H-[1,2,4]triazol-3-yl)-pyridine

Participants

Reaction Steps

84 microl (0.21 mmol, 2.5 M) n-BuLi was added dropwise to a solution of 37 mg (0.21 mmol) 4-(4,5-dimethyl-4H-[1,2,4]triazol-3-yl)-pyridine in 2.1 ml THF at 0° C. After 20 min a solution of 60 mg (0.21 mmol) 3-(1-bromo-ethyl)-5-(3-chloro-phenyl)-[1,2,4]oxadiazole was added dropwise. The reaction mixture was allowed to reach room temperature and stirred over night. NH4Cl(sat) was added and the mixture was extracted twice with EtOAc. The organic phase was dried and concentrated. Flashchromatography (CH2Cl2/MeOH 20:1) afforded 7.7 mg (10%) of the desired product. 1H NMR (CDCl3), d (ppm): 1.57 (d, 3 H) 3.16 (m, 1 H) 3.38 (m, 1 H) 3.71 (s, 3 H) 3.84 (d, 1 H) 7.46 (t, 1 H) 7.55 (m, 1 H) 7.58 (m, 2 H) 7.98 (m, 1 H) 8.10 (t, 1 H) 8.77 (d, 2 H)
