Electric Literature of 36805-97-7, 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. 36805-97-7, name is 1,1-Di-tert-butoxy-N,N-dimethylmethanamine belongs to ethers-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
1,1-Di-teit-butoxy-N,N-dimethylmethanamine (6.77 ml, 28.3 mmol) was added to asuspension of 2-({[(benzyloxy)carbonyl]amino}methyl)- 1-ethyl-i H-i, 3-benzodiazole-6- carboxylic acid, Intermediate 4 (2.50 g, 7.08 mmol) in a,a,a-trifluorotoluene (50 ml). The reaction mixture was heated at 100 00 for 1 h. The reaction mixture was allowed to cool to RT then i,i-di-teit-butoxy-N,N-dimethylmethanamine (6.77 ml, 28.3 mmol) was added dropwise over 15 mm. The resultant mixture was heated at 100 00 for 45 mm. Thereaction mixture was cooled to 50 00 then i,i-di-teit-butoxy-N,N-dimethylmethanamine (3.38 ml, 14.2 mmol) was added dropwise over 5 mm. The resultant mixture was heated at 100C for 0.5 h then allowed to cool to RT. The reaction mixture was partitioned between EtOAc (50 ml) and water (50 ml). The phases were separated then the organic phase was washed with water (2 x 30 ml), saturated aqueous NaHCO3 solution (20 ml)and brine (10 ml) then dried over Na2504, filtered and concentrated in vacuo to afford a beige solid (2.5 g). The solid thus obtained was suspended in MeCN (10 ml). The solid was collected by filtration then dried under vacuum to afford the product as an off-white solid (2.30 g, 79%).1H NMR (500 MHz, DMSO-d6) O 8.07 (5, 1H), 7.97 (m, 1H), 7.76 (dd, J= 8.4, 1.5 Hz,1 H), 7.64 (d, J = 8.4 Hz, 1 H), 7.34 (m, 5H), 5.07 (5, 2H), 4.55 (d, J = 6.0 Hz, 2H), 4.38 -4.25 (m, 2H), 1.57 (5, 9H), 1.29 (m, 3H).LC/MS (System A): m/z (ESl) = 410 [MH], R = 1.17 mi UV purity = 99%.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 1,1-Di-tert-butoxy-N,N-dimethylmethanamine, other downstream synthetic routes, hurry up and to see.
