Procedure

The title compound was prepared from 1-perhydro-2H-pyran-2-yl-3-(3-thienyl)-1H-indazole-5-carbonitrile (0.233 g, 0.75 mmol), azidotributyl tin (0.375 g, 0.3 10 mL, 1.13 mmol) in toluene (10 mL) as described for the preparation of Example 167. Deprotection was effected by treating a dioxane solution (5 mL) with 5 mL of 6.0N aqueous solution of hydrogen chloride. The solid obtained upon completion of the reaction was partially dissolved in 3 mL of tetrahydrofuran and was precipitated out by adding 20 mL of hexanes (0.108 g, 0.85 mmol, 79% yield over 2 steps): 1H NMR (DMSO-d6) δ 13.5 (br s, 1H), 8.8 (s, 1H), 8.2 (t, 1H), 8.1 (dd, 1H), 7.8–7.7 (m, 3H); ES-MS (m/z) 269 [M+1]+.
