Reaction Steps

A solution of 2-phenoxycarbonylamino-N-(1-phenoxylcarbonylpiperidin-4-yl)benzamide (1.6 g, 3.5 mmol) and n-heptylamine (0.45 g, 3.9 mmol) in toluene (20 ml) was refluxed for 4 hours and then concentrated. The residue was purified by column chromatography on silica gel (50% ethyl acetate in petroleum ether) to give 2-(N'-n-heptylureido)-N-(1-phenoxy carbonylpiperidin-4-yl)benzamide: yield 95.0%: mp 142°-144° C.; 1H NMR (CDCl3)ppm: 0.88 (3H, t) 1.28-1.33 (7H, m), 19-1.62 (4H, m), 2.05-2.17 (2H, m), 3.04-3.19 (2H, m), 3.25 (2H, q), 4.10-4.15 (1H, m), 4.24-4.40 (2H, m), 4.59 (1H, t), 6.35 (1H, d), 6.92 (1H, t), 6.97-7.44 (8H, m), 8.40 (1H,d), 10.20 (1H, s).
