In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact.76176-87-9, Thiomorpholine-1-oxide hydrochloride it is a common compound, a new synthetic route is introduced below., 76176-87-9
To a solution of acid 1 (50 mg, 0.1 1 mmol) in DMF (1 mL) was added N- methylmorpholine (49 pL, 0.45 mmol) followed by PyBOP (87 mg, 0.17 mmol). The reaction mixture was stirred for 30 min at rt before addition of thiomorpholine-1 -oxide hydrochloride (35 mg, 0.22 mmol). After 3 h 30 min the reaction mixture was diluted with EtOAc (30 mL), washed with HCI solution (5%, 3 x 10 mL) and brine (10 mL), before being dried over MgS04, filtered and concentrated in vacuo. Purification by flash column chromatography with EtOAc/MeOH (1 :0 to 4:1 ) and subsequent trituration with Et20 afforded FU as pale beige solids (16 mg, 27%). (1390) LCMS (ES): Found 550.9 [M+Hf.

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. 76176-87-9. We look forward to the emergence of more reaction modes in the future.
