实验步骤: HATU (30 mg, 0.079 mmol) was added to a stirring solution of 13-cyclohexyl-10-((isopropylsulfonyl)carbamoyl)-3-methoxy-7H-indolo[2,1-a][2]benzazepine-6-carboxylic acid (34 mg, 0.063 mmol) and 8-methyl-1,8-diazaspiro[4.5]decane (24 mg, 0.16 mmol) in DMF (0.5 mL) and TEA (100 μL, 0.72 mmol) and the reaction mixture was stirred at rt for 1 h (complete by LCMS). The reaction mixture was diluted with MeOH, filtered and purified by preparative HPLC (CH3CN/H2O w/10 mM NH4OAc) to yield 13-cyclohexyl-N-(isopropylsulfonyl)-3-methoxy-6-((8-methyl-1,8-diazaspiro[4.5]dec-1-yl)carbonyl)-7H-indolo[2,1-a][2]benzazepine-10-carboxamide (19.7 mg, 0.029 mmol, 46% yield) as a yellow solid. 1HNMR (300 MHz, CD3OD) δ ppm 1.10-2.20 (m, 22H), 2.76 (s, 3H), 2.67-3.49 (m, 9H), 3.91 (s, 3H), 3.86-4.00 (m, 1H), 4.27-4.45 (m, 1H), 5.07-5.20 (m, 1H), 6.91 (s, 1H), 7.03 (d, J=2.6 Hz, 1H), 7.13 (dd, J=8.8, 2.6 Hz, 1H), 7.56 (d, J=8.8 Hz, 1H), 7.73 (dd, J=8.4, 1.5 Hz, 1H), 7.81 (d, J=8.4 Hz, 1H), 8.26 (br s, 1H). LC-MS retention time: 2.64 min; m/z 671 (MH−). LC data was recorded on a Shimadzu LC-10AS liquid chromatograph equipped with a Phenomenex-Luna 10u C18 4.6×50 mm column using a SPD-10AV UV-Vis detector at a detector wave length of 220 nM. The elution conditions employed a flow rate of 5 mL/min, a gradient of 100% solvent A/0% solvent B to 0% solvent A/100% solvent B, a gradient time of 4 min, a hold time of 1 min, and an analysis time of 5 min where solvent A was 5% acetonitrile/95% H2O/10 mM ammonium acetate and solvent B was 5% H2O/95% acetonitrile/10 mM ammonium acetate. MS data was determined using a Micromass Platform for LC in electrospray mode.
