Participants

Reaction Steps

A solution of 3-ethyl-1-methyl-1-(4-methyl-2-(pyridin-3-yl)thiazol-5-yl)thiourea (70 mg, 0.239 mmol) and iodoethane (74.7 mg, 0.479 mmol) in ethanol (5 mL) was heated at 80° C. for 6 h in a sealed tube. Upon cooling the solvent was removed under reduced pressure and the residue purified via silica gel chromatography (0 to 100% ethyl acetate/hexanes) to furnish the title compound as a clear oil (30 mg, 39%): 1H NMR (400 MHz, CDCl3) δ 9.10 (d, J=2.0 Hz, 1H), 8.64 (dd, J=4.6 Hz, 1.4 Hz, 1H), 8.20 (d, J=4.2 Hz, 1H), 7.41-7.37 (m, 1H), 3.63 (q, J=7.6 Hz, 2H), 3.22 (s, 3H), 2.72 (q, J=7.8 Hz, 2H), 2.38 (s, 3H), 1.28-1.17 (m, 6H); ESIMS m/z 321 (M+1).
