Some tips on 1-(Methylsulfonyl)piperazine hydrochloride

161357-89-7 1-(Methylsulfonyl)piperazine hydrochloride 16265612, apiperazines compound, is more and more widely used in various fields.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.161357-89-7,1-(Methylsulfonyl)piperazine hydrochloride,as a common compound, the synthetic route is as follows.

2-Chloro-4-morpholinofuro[3,2-d]pyrimidine-6-carbaldehyde 39 prepared following Example 20 (65 mg, 1.0 eq) was dissolved in 1 ,2-dichloroethane (9.7 ml) and treated with hydrochloride salt of 1-methanesulfonylpiperazine (69 mg, 1.4 eq), sodium acetate (28 mg, 1.4 eq) and trimethyl orthoformate (0.27 ml, 10 eq). Reaction mixture was stirred at r.t. for 12 h. Sodium triacetoxyborohydride (62 mg, 1.2 eq) was added and reaction mixture was stirred at r.t. for 8 h. Reaction mixture was quenched with saturated aq. NaHCO3 and extracted with dichloromethane. The combined organic layers were dried (Na2SO4) and concentrated. The crude reaction mixture was purified by flash chromatography to yield 2- chloro-6-((4-(methylsulfonyl)piperazin- 1 -yl)methyl)-4-morpholmofuro [3 ,2-d]pyrimidine(70 mg, 68%) : MS (Ql) 416 (M)+., 161357-89-7
