1,1-Dimethylethyl 5,6-dihydroimidazo[1,2-a]pyrazine-7(8H)-carboxylate (I18) (1.563 g, 7 mmol) and NCS (0.935 g, 7.00 mmol) were heated at 80° C. for 2 h in toluene (30 mL). The solvents were removed in vacuo and the residue was purified by flash chromatography (Isolera, 50 g, 0-100% ethyl acetate/iso-hexane) to afford product in 1.55 g.
