3.89 g | With triethylamine; In isopropyl alcohol; for 5.0h;Reflux; | Piperidin-4--ol (1.65 g, 16.3 mmol), 2-chioro-4-(trifluoromethyl)pyrimidine (2.98 g,16.3 mmoi), and triethylamine (4.5 mL, 32.7 mmol) were refluxed in isopropanol (60 mU) for 5h. The reaction was cooled to room temperature and diluted with hexanes causing a white precipitate to fOrm. The solids were removed by filtration, and the filtrate was passed through a plug of silica, washing with 1: 1 EtOAc/hexanes and then EtOAc, The combined filtrate and washings were concentrated to dryness to afford 3,89 g of the title compound. Exact mass calculated for C,0H7F3N,O: 247,09, found: LCMS rn/a = 248.2 [M±H1*. |

With methanesulfonic acid; In 1,4-dioxane; at 100℃; for 24h; | Methanesulfonic acid (0.37 mL, 5.7 mmol) was added to a solution of 2-chloro- 4-trifluoromethyl-pyrimidine (0.90 g, 5.0 mmol) and <strong>[16618-68-1]3-bromo-5-methoxyaniline</strong> (1.0 g, 5.0 mmol) in dioxane (10 mL). The reaction was stirred at 100 C for 24 hours. The reaction mixture was cooled to 25 C, filtered and washed with diethyl ether. The filtrate was concentrated under reduced pressure to afford N-(3-bromo-5-methoxyphenyl)-4- (trifluoromethyl)pyrimidin-2-amine. MS ESI calcd. for C,2H,0BrF3N3O [M+H] 348 and 350, found 348 and 350. ?H NMR (500 MHz, CD3OD) oe 8.73 (d, J= 4.8 Hz, 1H), 7.54 (s, 1H), 7.46 (s, 1H), 7.16 (d, J= 4.9 Hz, 1H), 6.67 (s, 1H), 2.70 (s, 3H). |
