139009-66-8, (S)-N-Boc-2,2-dimethyloxazolidine-4-carboxylic Acid is a oxazolidine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To a solution of (4S)-3-(tert-butoxycarbonyl)-2,2-dimethyl-l,3-oxazolidine-4- carboxylic acid (0.56 g, 2.3 mmol) in dry JV,iV-dimethylacetamide (10 mL) was added HATU (0.11 g, 2.87 mmol) and DIEA (0.742 g, 5.75 mmol). After the reaction solution was stirred at rt for 1 h, 6-(4-aminophenyl)-Lambda^-(4-{[2-(trifluoromethyl)pyridin-4- yl]oxy}phenyl)pyrimidine-2,4-diamine (0.84 g, 1.92 mmol) was added. The solution was stirred for an additional 24 h at rt and separated by preparative HPLC to afford a solid intermediate, which was treated with methanol (10 mL) and concentrated HCl (0.5 mL) for 12 h at rt. The resulting mixture was diluted with DMSO and purified by HPLC to give a solid. The solid was stirred with saturated sodium bicarbonate and EtOAc for 2 h. The organic layer was separated, washed with water and brine, dried over magnesium sulfate, and evaporated to afford 0.433 g (43%) of pure product. 1H NMR (DMSO-J6) delta 9.34 (s, IH), 8.59 (d, IH), 7.88 (m, 4H), 7.76 (d, 2H), 7.37 (s, IH), 7.16 (m, 3H), 6.45 (s, IH), 6.36 (s, 2H), 4.88 (t, IH), 3.56 (m, 2H), 3.39 (m, IH); MS ES 526 (M+H)+ calcd 526.
139009-66-8, The synthetic route of 139009-66-8 has been constantly updated, and we look forward to future research findings.
