Triethylamine → HCID 89872730, compound

To a round bottom flask containing 4-bromobenzaldehyde (1.4 g, 7.80 mmol), 2-oxobut-3-enyl acetate (1 g, 7.80 mmol) and 3-benzyl-5-(2-hydroxyethyl)-4-methyl-thiazolium chloride (0.21 g, 0.78 mmol) was added dioxane (20 ml). The mixture was stirred at room temperature and triethylamine (0.65 ml, 0.60 mmol) was added. The reaction mixture was heated to 80 C for overnight. Afterward, the reaction was cooled down to room temperature, quenched with a solution of saturated ammonium chloride and concentrated. The residue was taken up in MTBE and washed with saturated ammonium chloride solution twice, then once with brine. The organic portion was dried over sodium sulfate, filtered and concentrated. The resulting crude material was purified by column chromatography to afford the title compound as a light orange solid after drying (1.63 g, 67% yield). MS (ESI) m/z 315.0 (M+1). Retention time 1.14 min. (Condition X).
