Participants

Reaction Steps

Compound 44E was prepared following the procedure as described for the synthesis of compound 44A (see Scheme 9) using pent-4-ynyl-cyclohexane and 3-(1-phenylsulfonyl-4-iodo-1H-pyrazol-3-yl)-pyridine (36B). (flash chromatography with diethyl ether/PE 1/1) to afford 3-[1-phenylsulfonyl-4-(5-cyclohexyl-pent-1-ynyl)-1H-pyrazol-3-yl]-pyridine (43E) as an oil (90%). 1H-NMR (400 MHz, CDCl3) δ 9.25 (d, J=2 Hz, 1H), 8.6 (dd, J=5 Hz, 2 Hz, 1H), 8.33 (dt, J=8 Hz, 2 Hz, 1H), 8.21 (s, 1H), 8.08-8.04 (m, 2H), 7.68 (bt, J=8 Hz, 1H), 7.57 (bt, J=8 Hz, 2H), 7.35-7.31 (m, 1H), 2.38 (t, J=7 Hz, 2H), 1.72-1.55 (m, 6H), 1.31-1.10 (m, 7H), 0.95-0.8 (m, 2H).
