참여 물질

반응 단계

HATU (40 mg, 0.105 mmol) was added to a solution of 2-(3-(trifluoromethyl)-4,5,6,7-tetrahydro-1H-indazol-1-yl)acetic acid (25.0 mg, 0.1 mmol) and DIPEA (0.02 mL, 0.12 mmol) in DMF (0.3 mL). After 10 minutes, 9D (26.5 mg, 0.1 mmol) in 0.2 mL of DMF was added to the reaction. The reaction was stirred for 2 hours. LC/MS shows desired product with a small amount of acid. Purified reaction mixture on prep reverse phase HPLC using 20-80% B over 20 min. (A=0.1% TFA/H2O; B=0.1% TFA/Acetonitrile). Combined pure fractions as determined by LC/MS and lyophilized to provide the desired compound. 1H NMR (400 MHz, DMSO) δ 9.02 (d, J=7.9 Hz, 1H), 7.96 (s, 1H), 7.58-7.42 (m, 3H), 7.30-7.18 (m, 2H), 7.18-7.06 (m, 3H), 7.00-6.86 (m, 2H), 5.06 (q, J=7.6 Hz, 1H), 4.74-4.61 (m, 2H), 2.98 (td, J=13.6, 6.4 Hz, 2H), 2.43 (s, 2H), 2.37-2.17 (m, 2H), 1.61 (d, J=5.9 Hz, 4H). MS (m/z) 495 [M+H]+.
