Reaction Steps

A solution of 1-(1-{[4-(bromoacetyl)-2-cyanoquinolin-7-yl]methyl}-1H-1,2,3-triazol-4-yl)-1-(trifluoromethyl)propyl 4-nitrobenzoate (see Example 52, Step 2) (65 mg, 0.1 mmol) and thioacetamide (9 mg, 0.11 mmol) in DMF (1 mL) was stirred at 100° C. overnight. The reaction mixture was diluted in ethyl acetate, washed with water, brine and dried over MgSO4. The crude compound was purified on silica gel (eluting solvent: 3% acetone in dichloromethane) to give the desired product. 1H NMR (acetone-d6): δ 8.85 (d, 1H), 8.52 (s, 1H), 8.42 (d, 2H), 8.30 (d, 2H), 8.17 (d, 2H), 8.05 (s, 1H), 7.75 (d, 1H), 6.05 (s, 2H), 3.05 (m, 1H), 2.85 (s, 3H), 2.85 (m, 1H), 1.15 (t, 3H).
