Reaction Steps

Part B: A mixture of tert-butyl 4-(pyridin-2-ylcarbamothioyl)piperazine-1-carboxylate (15.30 g, 47.5 mmol), potassium carbonate (13.10 g, 95.0 mmol), iodomethane (3.00 mL, 47.5 mmol), and DMSO (200 mL) was stirred at 25° C. for 24 h. The reaction mixture was diluted with ethyl acetate, washed with water (×4) and brine, dried over anhyd. sodium sulfate, filtered, and concentrated to provide tert-butyl 4-(methylthio(pyridin-2-ylimino)methyl)piperazine-1-carboxylate (12.00 g) as a waxy solid; 1H NMR (300 MHz, CDCl3) δ 8.25 (m, 1H), 7.63 (m, 1H), 6.88 (m, 2H), 3.70 (m, 4H), 3.52 (m, 4H), 2.04 (s, 3H), 1.44 (s, 9H).
