반응 단계

Zinc dust (106.5 mg, 1.63 mmol) in THF/H2O (2:1, 7.5 mL) was sonicated 15 minutes and 5-(2-Methylsulfanyl-pyrimidin-4-yl)-thiophene-2-sulfonyl chloride (500 mg, 1.63 mmol) was added all at once as a solid. After 22 hours, the mixture was concentrated to ¼ volume and a precipitate formed. Water was added and the suspension was sonicated for 1 minute. The solids were collected by filtration, washed with water and dried in vacuo to afford bis-5-(2-Methylsulfanyl-pyrimidin-4-yl)-thiophene-2-sulfonyl Zinc as a light yellow solid (1.3 g, >100%). This material was used in the next step. 1H NMR (500 MHz, DMSO-d6) δ 2.52 (s, 3H), 7.15 (d, J=3.5 Hz, 1H), 7.59 (d, J=5.5 Hz, 1H), 7.88 (d, J=3.5 Hz, 1H), 8.54 (d, J=5.5 Hz, 1H).
