Reaction Steps
A mixture of 1-bromo-3,3-dimethyl-butan-2-one (1.35 mL, 10 mmol) and thio-semicarbazide (0.91 g, 10 mmol) in ethanol (35 mL) was refluxed for 1.5 h and evaporated. Purification by flash chromatography (SiO2) provided (4-tert-butyl-thiazol-2-yl)-hydrazine (1.01 g, 59% yield) as an orange solid. 1H-NMR (DMSO-d6, 500 MHz) 9.0 (br, 1H), 7.3 (br, 2H), 6.37 (s, 1H), 1.22 (s, 9H) ppm; MS (LC-MS) 172.1 (M+H); HPLC (method A) 2.520 min.
