The synthetic route is as follows., COA of Formula: C8H7F2NO2
Methyl 2-amino-4,5-difluorobenzoate (14) (250 mg, 1.33 mmol) was dissolved in 4mL DMF. TEA (2.5 eq) and R-tert-butyl(pyrrolidin-3-yl methyl) carbamate (298.5 mg, 1.47 mmol) were added and stirred at 80 C for 5 h. The reaction mixture was dissolved in 20 mLDCM and washed with 10 mL water three times. The organic layer was concentrated by rotary evaporation. The residual DMF was removed by placing under high vacuum overnight. The residue was purified by silica gel chromatography using gradient from 3:1Hexanes:EtOAc to 1:1 Hexanes:EtOAc to yield pure UICK-II-189(15) Yield 73%. 1H NMR (300 MHz, CDCl3) d 7.43 (d, J 15.4 Hz,1H), 5.73 (d, J 7.8 Hz, 1H), 4.70 (bs, 1H, exchangeable), 3.82 (s, 3H),3.53 (m, 3H), 3.20 (m, 3H), 2.47 (m, 1H), 2.08 (m, 1H), 1.71 (m, 1H),1.47 (s, 9H). 19F NMR (282 MHz, CDCl3) d 141.00 (s, 1F). MS (ESI) calculated for (M H) 368.19, found 368.0.
According to the analysis of related databases, 207346-42-7, the application of this compound in the production field has become more and more popular.
