Acetoxyacetyl chloride (0.071 mL, 0.66 mmol) was added to a solution of (1R,2S)-1-(1-(4-fluorophenyl)-6-methyl-1H-indazol-5-yloxy)-1-phenylpropan-2-amine (62 mg, 0.17 mmol) and triethylamine (0.18 mL, 1.3 mmol) in THF (2.5 mL) at r.t. The mixture was stirred overnight and concentrated. The residue was dissolved in methanol (2 mL) and 28% ammonia (2 mL) and stirred at r.t. overnight. The title compound (57 mg, 80%) was obtained after purification by semi-preparative HPLC.
