실험 절차
A solution of (2-amino-4-methoxy-3-methylphenyl)(methyl)ketone (18.6 g, 104 mmol) in dioxane (50 mL) was added under nitrogen to a suspension of 4-isopropylthiazole-2-carbonyl chloride in dioxane (250 mL). After 2 h at room temperature, the reaction mixture was concentrated to dryness. Then, the residue was partitioned between an aqueous solution of NaHCO3 and AcOEt, organic layer was washed with brine, dried (Na2SO4), and evaporated. The residue was triturated in diisopropyl ether, filtered off and washed with diisopropyl ether to give 30.8 g (90%) of the title product 35.
