Synthetic Route of 4415-73-0, Adding some certain compound to certain chemical reactions, such as: 4415-73-0, name is 1,1-Cyclobutanedimethanol,molecular formula is C6H12O2, 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 4415-73-0.
Add 2.6 ml of an 11.25N sodium hydroxide solution at 70 C. to a solution of 1.72 g (14.85 mmol) of cyclobutane-1,1-diyldimethanol [F. X. Tavares, J. Med. Chem. 2004, 47 (21), 5057-5068] in 20 ml of toluene, 8 ml of 1,2-dimethoxyethane and 8 ml of water. After adding 0.10 g (0.30 mmol) of tetra-n-butylammonium hydrogen sulphate and 1.00 g (2.97 mmol) of 4-chloro-5-(4-methoxyphenyl)-6-phenylfuro[2,3-d]pyrimidine, stir the reaction mixture at 70 C. for 17 h. After cooling to room temperature, adjust to pH 7 with concentrated hydrochloric acid. Extract three times with 50 ml of dichloromethane each time. Wash the combined organic extracts with satd. sodium chloride solution, dry over sodium sulphate and filter. Concentrate the filtrate under reduced pressure. Stir the residue in acetonitrile, filter and purify the filtrate by means of preparative RP-HPLC (gradient: water/acetonitrile). 0.30 g (24% of theory) of the desired product are obtained. LC-MS (Method 3): Rt=2.67 min; m/z=417 (M+H)+ 1H-NMR (400 MHz, DMSO-d6): delta=8.58 (s, 1H), 7.56-7.54 (m, 2H), 7.42-7.37 (m, 5H), 7.04-6.99 (m, 2H), 4.56 (t, 1H), 4.30 (s, 2H), 3.81 (s, 3H), 3.21 (d, 2H), 1.77-1.58 (m, 6H).
According to the analysis of related databases, 4415-73-0, the application of this compound in the production field has become more and more popular.
