実験手順
To a suspension of [5-chloro-4-(3-chloro-5-cyanophenoxy)-1H-1,2,3-benzotriazol-1-yl]acetic acid (15 mg, 0.041 mmol) (see step 2 in Example 16) in DCM (0.5 mL) was added oxalyl chloride (58 mg, 0.454 mmol). This was followed by addition of DMF (1 drop) and then, following bubbling cessation, by addition of 2-chloroaniline (158 mg, 1.239 mmol). After 10 minutes, the reaction mixture was concentrated, taken up in DMF/MeOH and purified by reverse phase chromatography, eluting with 30-95% MeCN/H2O+0.1% TFA. The product fraction was lyophilized to yield the title compound. 1H NMR (DMSO-d6) δ 10.2 (s, 1H), 7.90 (d, J=9.0 Hz, 1H), 7.83 (m, 2H), 7.75 (d, J=8.3 Hz, 1H), 7.55 (m, 3H), 7.34 (m, 1H), 7.24 (m, 1H), 5.85 (s, 2H). HRMS (M+1)=472.0152.
