Reaction Steps

To the stirred solution of methyl 2-(3,4-dichlorophenyl)ethanimidothioate hydroiodide (0.184 g, 0.51 mmol) in dry DMSO (1 mL) were added 2-((2-oxo-1,2,3,4-tetrahydroquinolin-6-yl)oxy)acetohydrazide (0.120 g, 0.51 mmol) and TEA (0.103 g, 1.02 mmol) and heated at 115° C. in a seal tube overnight. Water was added to the reaction mixture. The solid precipate was filtered, dried and purified by preparative HPLC on a Kromasil C4 column (250×20 mm) using a gradient of ACN in 0.1% TFA (0-100%) to give 6-((5-(3,4-dichlorobenzyl)-4H-1,2,4-triazol-3-yl)methoxy)-3,4-dihydroquinolin-2(1H)-one as an off white solid (0.070 g; 34%). 1HNMR 400 MHz, DMSO-d6: δ 2.40 (t, J=7.20 Hz, 2H), 2.82 (t, J=8.00 Hz, 2H), 4.09 (s, 2H), 5.01 (s, 2H), 6.75-6.76 (m, 2H), 6.88 (s, 1H), 7.28 (d, J=8.40 Hz, 1H), 7.59 (d, J=8.00 Hz, 2H), 9.91 (s, 1H), 13.87 (bs, 1H). LCMS: RT 1.71 min; LCMS (ES-API), m/z 403.0.
