Reaction Steps

(55 mg, 173 μmol) 1-(5-Iodo-pyrimidin-2-yl)-4,4-dimethyl-imidazolidin-2-one (Example 122, step 1) was dissolved in DMF (1 ml) and cooled to 0-5° C. NaH (55%) (9 mg, 225 μmol, 1.3 equiv.) was added and the mixture was stirred for 30 min at 0-5° C. Iodomethane (13 μl, 200 mmol, 1.2 equiv.) was added and the mixture was stirred for 30 min without cooling bath. The reaction mixture was treated with sat. NaHCO3 solution and extracted twice with a small volume of CH2Cl2. The organic layers were loaded directly to silica gel column and the crude material was purified by flash chromatography on silica gel (20 gr, ethyl acetate/heptane gradient, 0:100 to 100:0). The desired 1-(5-iodo-pyrimidin-2-yl)-3,4,4-trimethyl-imidazolidin-2-one (31 mg, 54% yield) was obtained as a white solid, MS: m/e=333.1 (M+H+).
