Synthetic Route of 36805-97-7, The chemical industry reduces the impact on the environment during synthesis 36805-97-7, name is 1,1-Di-tert-butoxy-N,N-dimethylmethanamine, I believe this compound will play a more active role in future production and life.
3-Hydroxy phenyl acetic acid-t-butyl ester (Reagent F) A stirred suspension of 3-hydroxy-phenyl acetic acid (1.52 g, 10 mmol) in anhydrous toluene (20 mL) was heated at 80 C. and N,N-dimethyl formamide-di-t-butyl acetal (9.6 mL, 40 mmol) was added when the solution became homogenous. After 0.5 h, the reaction mixture was cooled to ambient temperature and the volatiles were distilled off in vacuo. The residue was diluted with water and extracted with diethyl ether (*2). The combined organic extract was dried over anhydrous sodium sulfate, filtered and evaporated in vacuo to afford an oil which was subjected to flash column chromatography over silica gel (230-400 mesh) using 16% ethyl acetate in hexane as the eluent to afford the title compound as a solid (1.17 g, 56%). 1H-NMR (300 MHz, CDCl3): delta1.47(s, 9H), 3.49(s, 2H), 6.30(s, 1H), 6.70-6.79 (m, 2H), 6.81(d, J=7.6 Hz, 1H), 7.16(t, J=7.7 Hz, 1H).
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.
