Reaction Steps

4-(5-Bromothiophen-2-yl)-pyrimidine thiol (2.5 g, 9.15 mmol) was completely dissolved in 14.8 mL DI water and 2.4 mL 4 N NaOH. The mixture was diluted with EtOH (25 mL) and MeI (0.598 mL, 9.61 mmol) was added. The reaction was stirred 18 hours. The yellow solids were collected by filtration, washed with EtOH and dried to afford 4-(5-Bromothiophen-2-yl)-2-methylsulfanyl-pyrimidine (2.32 g, 88.6%) as a pale yellow solid. MS: m/z 287 (M+H+).
