With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.76176-87-9,Thiomorpholine-1-oxide hydrochloride,as a common compound, the synthetic route is as follows.
To the stirred solution of 3-(4-amino-5-iodo-pyrrolo[2,3-d]pyrimidin-7-yl)-cyclobutanone (Step S.1 ; 680 mg, 2.05 mmol), 1.2-dichloroethane (55 ml) and diisopropylethylamine (1 .79 ml, 10.25 mmol) was subsequently added 1 -oxo-thiomorpholine hydrochloride (638 mg, 4.10 mmol) and sodium triacetoxyborohydride (652 mg, 3.08 mmol) at 0 C. The reaction mixture was stirred for 1 h at room temperature, and then poured into the stirred mixture of water (150 ml) and EtOAc (150 ml). The precipitate was filtered and washed with water and EtOAc. The solid collected was dried in vacuo to afford the title compound as beige crystals. HPLC-MS: M+H = 432.1 (R, = 0.43); TLC; R, = 0.36 (DCM/MeOH/NH3aq, 200:20:1 ).
The synthetic route of 76176-87-9 has been constantly updated, and we look forward to future research findings.
