With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.873397-34-3,Tetrahydro-2H-pyran-3-carboxylic acid,as a common compound, the synthetic route is as follows.
873397-34-3, Step 1 : To a solution of (3-methoxy-5-methylpyrazin-2-yl)methanamine (150 mg, 979.2 u mol), tetrahydro-2H-pyran-3-carboxylic acid (127.4 mg, 979.2 Mmol) in DCM (10 mL) was added HATU (670.2 mg, 1.8 mmol) and triethylamine (198.2 mg, 1.9 mmol). The mixture was stirred at 25¡ãC for 16 hours. The mixture was diluted with water (15 mL), extracted with DCM (3 x 30 mL). The combined organic layer was washed with brine (30 mL), dried over Na2S04, filtered and concentrated. The residue was purified by preparative TLC (EA/MeOH=20/1 ) to give N-((3-methoxy-5-methylpyrazin-2-yl)methyl)tetrahydro-2H-pyran-3- carboxamide (130 mg, 50percent yield).
As the paragraph descriping shows that 873397-34-3 is playing an increasingly important role.
