YieldReaction ConditionsOperation in experiment
62% With potassium carbonate; In N,N-dimethyl-formamide; at 80℃; for 1.16667h; Example 126: Preparation of 5-difluoromethoxy-l-(4-methoxy-benzylVl//-[l,2,31- triazole-4-carboxylic acid ethyl esterTo a solution of 5-hydroxy-l-(4-methoxy-benzyl)-lH-[l,2,3]triazole-4-carboxylic acid ethyl ester (1.0 g, 3.606 mmol) (Example 124) in N,N-dimethylformamide (IS ml) was added potassium carbonate (1.568 g, 11.36 mmol). The reaction mixture was heated to 8CPC and <strong>[383-62-0]ethyl 2-chloro-2,2-difluoroacetate</strong> (1.715 g, 10.8 mmol) added at 8CPC over 10 minutes. The reaction mixture was stirred at 8CPC for 1 hour. The reaction mixture was allowed to cool to room temperature and was quenched by addition of water (5 ml), ethyl acetate (10 ml) and aqueous hydrochloric acid (2M) (9 ml). The phases were separated and the aqueous phase extracted twice with more ethyl acetate. The combined organic extracts were washed with brine, dried over magnesium sulfate and concentrated. The residue was purified by column chromatography on silica gel (eluent: 10-40% ethyl acetate in hexane) to give 5-difluoromethoxy-l-(4-methoxy-benzyl)-lH-[l,2,3]triazole-4- carboxylic acid ethyl ester of a straw coloured oil which solidified on standing (0.726 g, 62% yield). <n="74"/>1H-NMR (400 MHz, CDCl3): 1.41 (t, 3H, Me), 3.80 (s, 3H, Me), 4.43 (q, 2H, CH2), 5.39 (s, 2H, CH2), 6.88 (d, 2H, CH), 7.3 (d, 2H, CH), 7.32 (t, IH, CHF2) ppm.
