In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 616-29-5, name is 1,3-Diaminopropan-2-ol, the common compound, a new synthetic route is introduced below. COA of Formula: C3H10N2O
Step 1[00207] l,3-diamino-2-propanol (XXXIX) (1.6 g, 17.75 mmol) was dissolved in water (3 ml/mmol, 53 mL) and then aq. 5% NaHC03 was added until pH was ~9, followed by acetone. The mixture was cooled to 0 C before adding a solution of B0C2O (7.74 g, 35.5 mmol) in acetone (2 mL/mmol, 35.5 ml) slowly dropwise over 2 h. The reaction mixture was allowed to warm to room temperature and stirred overnight. The acetone was evaporated under vacuum and the aqueous residue was washed with Et20 (x3). The organic layers were combined and dried over anhydrous MgS04. The solvent was removed under reduced pressure to give the crude product as a dark yellow oil. The crude product was crystallized from Et20/hexane to give tert- butyl 2-hydroxypropane-l,3-diyldicarbamate (XL) (3.71 g, 12.78 mmol,72% yield). 1H NMR (CDCI3) delta ppm 1.40 (s,18H), 3.06-3.27 (m, 4H), 3.61-3.67 (m, 1H), 4.00 (brs, 1H), 5.16-5.4 (m, 2H). ESIMS found for Ci3H26N205 m/z 313.6 (M+Na).
The synthetic route of 616-29-5 has been constantly updated, and we look forward to future research findings.
