反応手順

(αS,βR)-β-{[1-(4-Fluorophenyl)-1H-indazole-5-yl]oxy}-α-methylbenzeneethanamine (80 mg, 0.22 mmol), as described in Example 1, is dissolved in 1.42 mL dichloromethane and ethylisocyanatoacetate (28.6 mg, 0.22 mmol) is dropwise added. After stirring for 45 min at r.t. the solvent is removed and the residue purified by chromatography (silicagel, eluents: hexane/ethylacetate). 85.4 mg (78.6%) of the title compound are obtained.
