Adding a certain compound to certain chemical reactions, such as: 16545-68-9, Cyclopropanol, 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, Safety of Cyclopropanol, blongs to alcohols-buliding-blocks compound. Safety of Cyclopropanol
Step 6: N-methyl-7-cyclopropoxy-6-nitro-1,2,3,4-tetrahydroisoquinoline N-methyl-7-fluoro-6-nitro-1,2,3,4-tetrahydroisoquinoline (150mg, 0.72mmol), sodium tert-butoxide (83mg, 0.86mmol) and N, N-dimethylformamide (5mL) were added to a 25ml reaction flask under nitrogen protection. The reaction was stirred for 10 minutes at 0C, and added with cyclopropanol (54mg, 0.93mmol) in N, N-dimethylformamide (5mL) solution. The reaction was stirred and reacted for 1 hour at 0C. After completion of the reaction, ethyl acetate and water were added to the reaction solution, and the reaction solution was extracted with ethyl acetate twice additionally. The combined organic phase was washed with saturated brine, dried and concentrated. The obtained crude product was separated and purified by column chromatography (silica gel column, eluent: ethyl acetate/petroleum ether, gradient: 0?50%) to obtain the title compound (140mg, 79%). (MS: [M+1] 249.1)
The synthetic route of 16545-68-9 has been constantly updated, and we look forward to future research findings.
