78.4% | 60% sodium hydride (12.0 g, 0.30 mol) was suspended in THF (300 mL) and cooled down to 0 C. 4-amino-6-bromo-2-methylpyrimidine (Compound 9) (18.7 g, 0.1 mol) was then added in batches and stirred for 30 min. After <strong>[72605-86-8]methyl 2-chlorothiazole-5-formate</strong> (Compound 10) (17.7 g, 0.1 mol) was added in batches, the reactants were heated and reacted by refluxing for 4 h, and then cooled down to room temperature for reaction overnight. When controlling the temperature between 0 C. and 5 C., hydrochloric acid (2N) was added for neutralization reaction. After adding keep heat and stirred to grow grains for 1 h. Filtrate and wash the cake with water, and then dry to give target Compound 11 (25.8 g, yield is 78.4%).[0177]Element analysis: C10H9BrN4O2S, Calculated: C, 36.49; H, 2.76; N, 17.02.
