반응 단계
To a suspension of 4-bromo-2-methyl-thiobenzamide (3.11 g, 13.5 mmol) and 2-chloromalonaldehyde (2.16 g, 20.3 mmol) in dimethoxyethane (20 ml) is added magnesium carbonate (567 mg, 6.75 mmol) and the resulting mixture stirred at 60° C. under N2 for 3 hours. The crude reaction is then filtered through a plug of silica, washed with EtOAc and the filtrate concentrated to give 2-(4-bromo-2-methyl-phenyl)-thiazole-5-carbaldehyde (3.8 g).
