Reaction Steps
A solution of ethyl 2-(2-amino-5-methylthiazol-4-yl)-2-(Z)-(hydroxyimino)acetate (8.73 g) in dimethylformamide (60 ml) was treated portionwise with trityl chloride (11.7 g) and dropwise with triethylamine (6.4 ml). The reaction mixture was quenched by water and extracted with ethyl acetate. The combined extracts were washed with water and brine, and were dried with magnesium sulfate. The solvent was removed under reduced pressure to afford ethyl 2-(Z)-hydroxyimino-2-(5-methyl-2-tritylaminothiazol-4-yl)acetate (16.15 g).
