87.9% | at 0 - 110℃; for 2.33333h; | Add morpholine(6.75g, 77.4 mmol) to a 100-mL 3-neck flask equipped with a reflux condenservia syringe. The flask was heated to 110 C, and 3,4-dichloro-1,2,5-thiadiazole(3.0 g, 19.3 mmol) was added dropwise over the course of 20 min . Once additionwas complete, the reaction was stirred at 110 C for 2 hours. The reactionmixture was cooled to 0 C in an ice bath. Water (30 mL) was added and themixture was made acidified with concentrated hydrochloric acid. The mixture wasstirred at 0 C and a precipitatecrashed out of solution. The solids werefiltered, washed with water, and dried.The orange solid was recrystallized from methanol and dried under highvacuum to yield 3.5 g (87.9%) of 4-(4-chloro-1,2,5-thiadiazol-3-yl)morpholine. 1HNMR (400 MHz, CDCl3) delta 3.45-3.55 (m, 2H), 3.80-3.90 (m, 2H).
