Reaction Steps

A mixture of 5-chloro-2-methyl-6-[(trimethylsilyl)ethynyl]imidazo[1,2-a]pyrazine (0.400 g, 1.52 mmol), and sodium sulfide nonahydrate (1.09 g, 4.55 mmol) in N,N-dimethylformamide (6.0 mL) was heated in a preheated oil bath at 100° C. with stirring for 1 h. The reaction was cooled and partitioned between EtOAc and water. The organic layer was washed with water, brine, dried and the solvent was removed in vacuo. The residue was chromatographed on silica gel eluting with EtOAc and 3% MeOH in EtOAc to give the desired product (0.15 g, 52%). LCMS calculated for C9H8N3S (M+H)+: m/z=190.0. Found: 190.0.
