New downstream synthetic route of 2-Amino-2-methyl-1-propanol

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,124-68-5, its application will become more common.

Adding a certain compound to certain chemical reactions, such as: 124-68-5, 2-Amino-2-methyl-1-propanol, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, 124-68-5, blongs to alcohols-buliding-blocks compound. name: 2-Amino-2-methyl-1-propanol

(1) Acetic acid (5.4 ml) was added to a solution of 2-amino-2-methyl-1-propanol (8.4 g) and benzaldehyde (10 g) in 1,2-dichloroethane (140 ml) under ice-cooling. After 30 minutes of stirring at the same temperature, sodium triacetoxyborohydride (26 g) was added by small portions to the solution over 10 minutes. After 2 hours of stirring at room temperature, the mixture was poured into a solution of sodium hydrogen carbonate (48 g) in water (300 ml). The aqueous layer was separated and adjuster to pH 12 with 24% sodium hydroxide aqueous solution. The alkaline solution was extracted with ethyl acetate 12 times. The extract was dried over sodium sulfate and evaporated under reduced pressure to give colorless crystals of 2-benzylamino-2-methyl-1-propanol (13.2 g). mp: 46.0-47.0 C. IR (Nujol): 3330, 3100, 2900, 1450, 1380, 1355 cm-1 NMR (DMSO-d6, delta): 0.99 (6H, s), 3.23 (2H, d, J=3.9Hz), 3.62 (2H, s), 4.50-4.60 (1H, m), 7.16-7.36 (5H, m)

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,124-68-5, its application will become more common.
