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
4-(tert-butoxycarbonyl)thiomorpholine-2-carboxylic acid (2.47 g, 10 mmol) and HOBt (1.62 g, 12 mmol) were dissolved in DMF (20 mL), and EDCl (2.11 g, 11 mmol) was added. The reaction mixture was stirred for 1 hour, and 25% aqueous ammonia (5 mL) was added, and the reaction was stirred for another 2 hours. The reaction was then diluted with EtOAc (200 mL) and partitioned with water (100 mL). The organic layer was washed with saturated aq. NaHCO3 (2*100 mL), and then dried with Na2SO4. The solvent was removed in vacuo to afford title compound as white solid 2.46 g. MS (m/z): 147 (M+H-Boc)+
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 .
