Conditions

Temperature: 60 °C

Procedure

A mixture of 4-(2-amino-3-nitrophenyl)carbonylamino-N-(2-hydroxy-4-methylphenyl)-3-methoxy-N-methylbenzamide (520 mg), N-(4-bromobutyl)phthalimide (326 mg) and potassium carbonate (160 mg) in N,N-dimethylformamide (10 ml) was heated at 60° C. for 8 hours. The mixture was diluted with ethyl acetate and the solution was washed with water and brine. The organic phase was dried over magnesium sulfate and the solvent was evaporated in vacuo. The crude oil was purified by silica gel column (1% methanol in chloroform) to give 4-(2-amino-3-nitrophenyl)carbonylamino-3-methoxy-N-methyl-N-[2-(4-phthalimidobut-1-yloxy)-4-methylphenyl]benzamide (670 mg).
