Reaction Steps

To a solution of methyl 3-[(5-fluoro-2-nitrobenzoyl)amino]-4-methylbenzoate (8 g) in DMSO (24 ml) was added N-isopropylpiperazine (3.4 g) and N,N-diisopropylethylamine (4.7 ml) and the reaction stirred at room temperature for 6 hours. Water (200 ml) was added and the resultant solid collected by filtration, washed with water (×3) and dried in vacuo at 50° C. for 16 hours to yield methyl 4-methyl-3-{[5-(4-isopropylpiperazin-1-yl)-2-nitrobenzoyl]amino}benzoate as a yellow solid (10.7 g); NMR Spectrum: (DMSOd6) 0.99 (d, 6H), 2.34 (s, 3H), 2.55 (m, 4H), 2.71 (m, 1H), 3.50 (m, 4H), 3.85 (s, 3H), 7.07 (m, 2H), 7.39 (d, 1H), 7.71 (m, 1H), 8.06 (d, 1H), 8.20 (m, 1H), 9.96 (s, 1H); Mass Spectrum: M+H+ 441.
