Participants

Reaction Steps

2-Amino-4-(1-cyclopropylmethyl-2-methylimidazol-5-yl)pyrimidine (Method 54; 2 g, 8.73 mmol) was treated with N-(2-methoxyethyl)-N-(t-butyl)-4-iodobenzenesulphonamide (Method 77; 3.82 g, 9.61 mmol) under the conditions described in Example 22. The reaction was quenched by the addition of acetic acid (250 μl, 4.37 mmol), the mixture was poured into water and extracted with EtOAc. The extracts were combined, washed with water and then brine, dried and the solvent removed by evaporation. The residue was purified by chromatography on silica gel eluting with DCM/MeOH (97:3) to give the title compound (1.4 g, 32%) as a pale yellow foam. NMR: 0.01 (m, 2H) 0.18 (m, 2H) 1.90 (m, H) 2.26 (s, 3H) 3.15 (s, 3H) 3.37 (m, 4H) 4.42 (d, 2H) 7.08 (d, H) 7.52 (s, H) 7.58 (d, 2H) 7.75 (d, 2H) 8.30 (d, H) 9.75 (s, H); m/z 499.
