Procedure

2-(3-(Trifluoromethyl)-4,5,6,7-tetrahydro-1H-indazol-1-yl)acetic acid (124 mg, 0.5 mmol) and 11F (200 mg, 0.5 mmol) were dissolved in 3 mL of DMF and cooled down to 0° C. To it were added N,N-diisopropylethylamine (435 μL, 2.5 mmol) and HATU (228 mg, 0.6 mmol). The reaction mixture was stirred at 0° C. for 5 minutes, and then partitioned between EtOAc and 5% LiCl aqueous solution. The organic layer was separated, washed with brine, dried over MgSO4, filtered and concentrated. The residue was dissolved in methylene chloride and to it added hexanes. The precipitate was collected by vacuum filtration and dried under high vacuum overnight to afford the title compound 11G. MS (m/z) 592.25 [M+H]+.
