Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 134676-67-8, name is N-Boc-2-thiomorpholinecarboxylic Acid. This compound has unique chemical properties. The synthetic route is as follows. 134676-67-8
Synthesis of Example 32 Thiomo holine-2,4-dicarboxylic acid 4-tert-butyl ester (10 g, 40.43 mmol) is dissolved in a mixture of dichloromethane (50 mL) and methanol (40 inL) and cooled to 0 C under N2. A solution of trimethylsilyldiazomethane (2M in diethyl ether, 44.5 mL, 89 mmol) is added dropwise with stirring, the mixture allowed to warm to room temperature and stirred overnight. The solvent is removed under vacuum, the residue dissolved in ethyl acetate and washed with water, dried over magnesium sulphate and the solvent removed under vacuum to give compound 32-1.Yield: 10.5 gES mass spectrum: [M+H-tBu]+ = 206Retention time HPLC : 1.76 min (UPLC Method 1 )
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant. 134676-67-8, we look forward to future research findings about .
