Procedure: First a solution of 17.4 g (0.1 mol) of azodicarboxylic acid diethyl ester in 50 ml of toluene is added dropwise at 10°-20° to a solution of 26.2 g (0.1 mol) of triphenylphosphine in 260 ml of toluene and then, at 5°-10°, a solution of 17.6 g (0.1 mol) of o-trifluoromethylbenzyl alcohol in 120 ml of a 1N solution of hydrazoic acid in toluene is added dropwise thereto and the whole is stirred at room temperature for 2 hours. The precipitated hydrazinodicarboxylic acid ester is filtered off with suction, the toluene solution is concentrated by evaporation and the residue is treated with cyclohexane. The cyclohexane solution is decanted off from the insoluble portions, filtered through a small amount of silica gel and concentrated by evaporation at 50° in vacuo. In this manner o-trifluoromethylbenzyl azide is obtained in the form of a colourless liquid. The precipitated hydrazinodicarboxylic acid ester is filtered off with suction the toluene solution is concentrated by evaporation the residue is treated with cyclohexane The cyclohexane solution is decanted off from the insoluble portions filtered through a small amount of silica gel concentrated by evaporation at 50° in vacuo

Procedure: To o-(trifluoromethyl)benzyl alcohol (35 mg, 0.20 mmol) in CH2Cl2 (4 mL) was added was a solution of carbonyl diimidazole (29 mg, 0.18 mmol) in CH2Cl2 (4 mL). The mixture was stirred at rt for 2 h. A 1-mL aliquot of the resulting solution (0.05 mmol) was added to a solution 7-bromospiro[indene-1,4′-piperidin]-3(2H)-one (14.5 mg, 0.05 mmol) in CH2Cl2 (1 mL). The mixture was stirred at rt for 16 h, concentrated, redissolved in MeCN (1 mL) and heated at 60° C. for 2 h. Prep HPLC afforded the title compound. LC-MS Method 1 tR=2.06, min, m/z=484, 482. The mixture was stirred at rt for 16 h concentrated redissolved in MeCN (1 mL) heated at 60° C. for 2 h

Procedure: A solution of 30 ml of phosphorus tribromide in 60 ml of absolute toluene was added dropwise at 20°-30° C. to a solution of 14 g of o-trifluoromethylbenzyl alcohol in 80 ml of absolute toluene. Subsequently, the reaction mixture was stirred at room temperature for 2 hours, the toluene was distilled under reduced pressure, the residue was dissolved in methylene chloride, treated with water and the mixture was adjusted to pH 8.0 with potassium hydrogen carbonate. The aqueous phase was extracted three times with CH2Cl2 and the organic phases were washed twice with water and once with saturated NaCl solution, dried over Na2SO4 and evaporated under reduced pressure. o-Trifluoromethylbenzyl bromide was obtained as the residue. the toluene was distilled under reduced pressure the residue was dissolved in methylene chloride treated with water The aqueous phase was extracted three times with CH2Cl2 the organic phases were washed twice with water and once with saturated NaCl solution dried over Na2SO4 evaporated under reduced pressure
