实验步骤: To a solution of 3-chloro-5-(tert-butyldimethylsilyloxy)benzoic acid (17.5 g, 60 mmol), as prepared in the preceding step, and CH2Cl2 (250 mL) were added triethylamine (33.8 mL, 0.24 mol) and bis(2-oxo-3-oxazolidinyl)phosphinic chloride (17.0 g, 66 mmol). The resulting mixture was stirred for 5 min, then N-allylcyclopentylamine (9.8 mL, 66 mmol) was added. After 1 h, the solution was filtered. The filtrate was washed with 10% aqueous HCl (100 mL), saturated aqueous NaHCO3 (100 mL), and brine (100 mL). The organic layer was dried over anhydrous MgSO4, concentrated in vacuo, and flash chromatographed to provide the title compound as a colorless oil (23.5 g, 97%). 1H NMR (CDCl3) δ 6.95 (s, 1H), 6.84 (s, 1H), 6.71 (s, 1H), 5.93 (br s, 1H), 5.16 (d, 2H), 3.95 (br s, 3H), 1.4-1.9 (m, 8H), 0.97 (s, 9H), 0.20 (s, 6H). Mass spectrum (CI) calcd. for C21H32NO2SiCl: 394 (M+H). Found: 394. After 1 h the solution was filtered The filtrate was washed with 10% aqueous HCl (100 mL), saturated aqueous NaHCO3 (100 mL), and brine (100 mL) The organic layer was dried over anhydrous MgSO4 concentrated in vacuo, and flash chromatographed

实验步骤: To a strrred solution of 3-[2-(tert-butoxycarbonyl-pyridin-4-yl-amino)-ethoxy]-5-chloro-benzoic acid (0.039 g), TBTU (0.064 g) and HOBt (0.027 g) in DMF (1 ml) was added DIPEA (0.036 ml) followed by N-allylcyclopentylamine (0.029 ml) after 15 min. The reaction mixture was stirred at room temperature for 18 h and then concentrated under reduced pressure. The residue was subjected to preparative hplc and the title compound (0.030 g) obtained by concentration of the required fraction under reduced pressure and drying by repetitive addition of acetonitrile and concentration under reduced pressure. concentrated under reduced pressure

实验步骤: 790 mg (0.48 ml, 3.99 mmol) of trichloromethylformate (“diphosgene”) are dissolved in 15 ml of dichloromethane and cooled to 0° C. To this are slowly added dropwise 1.00 g (1.17 ml, 7.986 mmol) of allyl(cyclopentyl)amine and 1.21 g (1.67 ml, 12.0 mmol) of triethylamine, and the mixture is left to stir at room temperature overnight. For workup, the reaction solution is poured into ice-water, extracted three times with dichloromethane, dried over MgSO4 and concentrated. The crude product is employed directly in the next stage. the mixture is left extracted three times with dichloromethane dried over MgSO4 concentrated
