Example 3-14-2 Preparation of 1-(2-Amino-1-(3-methoxy-4-((6-methoxypyridin-3-yl)methoxy)benzyl)-1H-benzo[d]imidazol-5-yl)-4-methylpiperazin-2-one To a stirred suspension of 5-iodo-1-(3-methoxy-4-((6-methoxypyridin-3-yl)methoxy)benzyl)-1H-benzo[d]imidazol-2-amine (0.25 g, 0.48 mmol) in 1,4-dioxane (8 mL) was added 4-methylpiperazin-2-one (0.11 g, 0.96 mmol), CuI (0.036 mg, 0.19 mmol), trans-N,N’-dimethylcyclohexane-1,2-diamine (0.044 g, 0.38 mmol), and tribasic potassium phosphate (0.32 g, 1.52 mmol). The mixture was heated to 145 C. in a microwave reactor. After 3 h, the mixture was allowed to cool to room temperature and was filtrated through Celite. The filtrate was concentrated, and the residue was purified by silica gel chromatography (2-5% methanol/dichloromethane elute) followed by prep-HPLC to afford 0.030 g (12%) of the product as a white solid: 1H NMR (500 MHz, CDCl3) delta 8.17 (s, 1H), 7.66 (dd, J=8.0, 2.0 Hz, 1H), 7.25 (s, 1H), 7.01 (d, J=8.0 Hz, 1H), 6.86 (d, J=8.0 Hz, 1H), 6.79 (d, J=8.0 Hz, 1H), 6.76-6.74 (m, 2H), 6.64 (d, J=7.5 Hz, 1H), 4.99 (s, 2H), 4.89 (br s, 2H), 4.81 (s, 2H), 3.94 (s, 3H), 3.79 (s, 3H), 3.72 (t, J=5.0 Hz, 2H), 3.30 (s, 2H), 2.82 (t, J=5.0 Hz, 2H), 2.44 (s, 3H) ppm; (M+1)=503., 34770-60-0
34770-60-0 4-Methylpiperazin-2-one 13704283, apiperazines compound, is more and more widely used in various fields.
