反応手順

To a stirred solution of 2-amino-4-(1-methoxyprop-2-yl-2-methylimidazol-5-yl)pyrimidine (Method 53; 118 mg, 0.75 mmol), N-(tetrahydrofur-2-ylmethyl)4-iodobenzenesulphonamide (Method 68; 413 mg, 1.13 mmol), tris(dibenzylideneacetone) dipalladium (0) (35 mg, 0.038 mmol) and 2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (47 mg, 0.076 mmol) in dioxane (10 mL) was added sodium t-butoxide (258 mg, 2.69 mmol) and the mixture heated at 80° C. overnight. The reaction was cooled to room temperature and MeOH (5 ml) was added and the mixture poured onto an Isolute SCX-2 column, eluted first with MeOH (10×30 ml) and the product was then eluted with 10% methanolic ammonia (10×30 ml). The solvent was removed by evaporation and the residue purified by flash chromatography on silica gel eluting with DCM/MeOH (100:0 increasing in polarity to 97:3) to yield a foam which was dissolved in MeOH (2 ml) and treated with 1M HCl in ether (300 μL, 0.30 mmol) for 5 minutes. Solvent was evaporated in vacuo to yield a yellow solid (115 mg, 30%). NMR: 1.52 (d, 3H), 1.75 (m, 4H), 2.70 (m, 2H), 2.79 (s, 3H); 3.16 (s, 3H), 3.63 (m, 5H), 5.65 (m, 1H), 7.25 (d, 1H), 7.56 (t, 1H), 7.70 (d, 2H), 7.88 (d, 2H), 8.21 (s, 1H), 8.68 (d, 1H), 10.19 (brs, 1H); m/z 487.
