Procedure

2-(3-Chloro-propyl)-2H-[1,2,4]triazolo[4,3-a]pyridin-3-one 211 mg (1 mmol was loaded into a round bottomed flask, followed by 396 mg (2eq) of 3-(1,2,3,6-Tetrahydro-pyridin-4-yl)-1H-indole, 1.0 gram of potassium iodide, 1.0 gram of potassium carbonate, 100 ml acetone. The mixture was stirred under nitrogen for 18 hours. It was then poured into about 300 ml water and extracted with ethyl acetate (2×200 ml). The combined organic layers were dried over magnesium sulfate and filtered and concentrated. Flash column chromatography using 10%˜100% ethyl acetate/hexane and yielded 220 mg of product (59%). mp: 173.3° C. M+:374.0; (300 MHz, CDCl3): 8.60 (s, 1H, NH), 7.90 (d, 1H), 7.75(d, 1H), 7.34(d, 1H), 7.11(m, 5H), 6.44(m, 1H), 6.16(s, 1H), 4.12 (t, CH2), 3.22 (d, CH2), 2.70 (t, CH2) 2.60(m, 4H), 2.17 (t, CH2).
