85 °C

A mixture of 5-tert-butyl-4-methylthiazole-2-ylamine (1.5 g, 8.8 mmol) and 2-bromoethyl methyl ether (0.91 mL, 9.7 mmol) was warmed to 85° C. and allowed to stir for 24 hours. The crude material was dissolved in ˜5 mL of a 1:1 mixture of CH2Cl2 and CH3OH and a small amount of silica gel was added. This mixture was concentrated to dryness and the residue was purified via flash column chromatography (SiO2, 9:1:0.1 CH2Cl2:CH3OH:NH4OH) to afford the title compound (1.0 g, 4.4 mmol, 50% yield). 1H NMR (300 MHz, CD3OD) δ ppm 1.41 (s, 9H) 2.38 (s, 3H) 3.35 (s, 3H) 3.66 (t, J=4.70 Hz, 2H) 4.16 (t, J=4.70 Hz, 2H); MS (DCI/NH3) m/z 229 (M+H)+.
