Reaction Steps

The title compound was prepared from 3-(4-chlorophenyl)-1-perhydro-2H-pyran-2-yl-1H-indazole-5-carbonitrile (0.351 g, 1.04 mmol), azidotributyl tin (0.351 g, 0.627 mL, 2.29 mmol) in toluene (10 mL) as described for the preparation of compound 167. Deprotection was effected by treating a dioxane solution (5 mL) with 5 mL of 6.0N aqueous solution of hydrogen chloride. Half of the solid obtained upon completion of the reaction was purified by preparatory HPLC (0.054 g, 0.18 mmol, 35% yield over 2 steps) 1H NMR (DMSO-d6) 13.7 (s, 1H), 8.8 (s, 1H), 8.1 (t, 3H), 7.8 (d, 1H), 7.6 (t, 2H); ES-MS (m/z) 297 [M+1]+.
