Yield: 93%
Reaction Conditions:
Stage #1:methanol;2-amino-4-thiazoleacetic acid with sulfuric acid in methanol at 0;Reflux;
Stage #2: with sodium hydrogencarbonate; pH=8 - 9
Steps:
1.1 Preparation of methyl (2-amino-1,3-thiazol-4-yl)acetate
Preparation of methyl(2-amino-1,3-thiazol-4-yl)acetate To a solution of 2-amino-4-thiazole acetic acid (20 g, 0.126 mol) in methanol (100 ml) was added concentrated H2SO4 (24 ml) dropwise at 0-5° C. and the reaction mixture was refluxed for 5 hours. Subsequently the reaction mixture was basified to pH of 8-9 with NaHCO3 solution, to give a colorless precipitate, which was filtered and dried to afford the title compound in 19.5 g (93% yield).
