With hydrogenchloride; trifluoroacetic acid; In hexane; dichloromethane; ethyl acetate; N,N-dimethyl-formamide; | (27c) 4-Chlorobenzoic acid (258 mg) was dissolved in DMF (8 mL) prior to the addition of Hunig's base (1.0 mL). After cooling to 0 C., BOP Reagent (729 mg) was added. This was stirred for 15 min before (1S,2R)-1-(N-(t-butoxycarbonyl))-1,2-cyclopentanediamine, (27b), (300 mg) was added as a DMF solution (2 mL). The resulting mixture warmed to rt and was stirred overnight. EtOAc was added along with 1 N HCl solution. The EtOAc layer was washed with 1 N HCl, NaHCO3 solution, and brine. The EtOAc was dried (MgSO4), filtered, and concentrated. The resulting material was dissolved in CH2Cl2 (10 mL) and cooled to 0 C. TFA (1.2 mL) was added and the reaction was stirred for 2 h. This solution was concentrated prior to the addition of DMF (8 mL). After cooling to 0 C., Hunig's base (1 mL) and <strong>[17794-48-8][[3-(trifluoromethyl)benzoyl]amino]acetic acid</strong> (386 mg) were added. BOP Reagent (655 mg) was added next, and the mixture was stirred overnight. EtOAc was added along with 1 N HCl solution. The EtOAc layer was washed with 1 N HCl, NaHCO3 solution, and brine. The EtOAc was dried (MgSO4), filtered, and concentrated. This was stirred in 1:1 EtOAc/hexane and then filtered to give the title benzamide N-[2-[[(1S,2R)-2-[(4-chlorobenzoyl)amino]cyclopentyl]amino]-2-oxoethyl]-3-(trifluoromethyl)benzamide (310 mg) as a solid. MS found: (M+H)+=468.2. |

57% | In water; N,N-dimethyl-formamide; | Example 3 Preparation of N-(3-hydroxypropyl)-2-anthraquinonecarboxamide (2) To a stirred suspension of <strong>[117-78-2]anthraquinone-2-carboxylic acid</strong> (Aldrich, 10.00 g, 39.64 mmol) in DMF (130 ml), was added (benzotriazol-1-yloxy)tris(dimethylamino)-phosphonium hexafluorophosphate (17.54 g, 39.66 mmol) and trethylamine (11.05 ml, 79.28 mmol). The resulting mixture (initially a clear green solution) was stirred at room temperature for 10 min. before dropwise addition of 3-amino-1-propanol (3.34 ml, 43.67 mmol). The reaction mixture (clear brown solution) was stirred at room temperature in the dark for 17 hours. The solution was poured in a thin stream into water (300 ml) containing some ice. The precipitated material was isolated by filtration and recrystallized from boiling 96percent ethanol (ca. 200 ml) and gave the title compound 2 as a bright yew solid (6.93 g, 57percent yield). 1H NMR (250 MHz, DMSO-d6) delta: 1.74 (2H, quintet, J=6.52 Hz, CH2), 3.25-3.44 (2H, m, CH2), 3.50 (2H, broad t, J=5.80 Hz, CH2), 4.53 (1H, broad s, OH), 7.76-8.00 (2H, m, Ar), 8.04-8.36 (4H, m, Ar), 8.56 (1H, d, J=1.55 Hz, Ar), 8.89 (1H, t, J=5.42 Hz, NH). 13C NMR (250 MHz, DMSO-d6) delta: 32.32, 36.96, 58.68, 125.50, 126.83, 126.85, 127.05, 132.79, 133.04, 133.08, 134.45, 134.66, 139.49, 164.62, 182.11. |
