Reaction Steps

By following the same procedure as that for BO-2091, BO-2147 was prepared from N-(3-aminophenyl)-3-(piperidin-1-yl)propanamide (2.47 g, 10.0 mmol) and N-mustard isocyanate [19, freshly prepared from N-mustard amine hydrochloride 18 (6.1 g, 20 mmol)] in dry DMF. Yield: 4.2 g (82%); mp 108-110° C. The HCl salt of compound BO-2147 was prepared by following the same procedure as that for compound BO-2091. 1H NMR (DMSO-d6) δ: 1.33-1.42 (1H, m, CH), 1.67-1.79 (5H, m, CH), 2.90-2.94 (4H, m, CH2), 3.30-3.33 (2H, m, CH2), 3.38-3.42 (2H, m, CH2), 3.69-3.74 (8H, m, CH2), 6.73-6.75 (2H, m, Ar—H), 7.16-7.18 (2H, m, Ar—H), 7.26-7.27 (3H, m, Ar—H), 7.72 (1H, s, Ar—H), 8.95 (1H, brs, NH), 9.14 (1H, brs, NH), 10.33 (1H, brs, NH). 13C NMR (CDCl3, 125 MHz) δ: 21.32, 22.37, 30.53, 40.89, 51.79, 52.13, 53.14, 108.79, 112.57, 113.03, 113.97, 119.99, 128.88, 139.31, 140.50, 152.87, 167.79.
