実験手順

(S)-2-Amino-1-(4-hydroxy-piperidin-1-yl)-3-(1H-imidazol-4-yl)-propan-1-one hydrochloride (0.7 mmol) and 5-chloro-1H-indole-2-carboxylic acid (0.7 mmol) were coupled according to Procedure A (120 hour reaction time, acid wash omitted). The crude product was triturated twice with ether, with 1:1 ether-hexanes and the residue purified by chromatography on silica gel eluted with 5-20% ethanol in dichloromethane containing 0.5% ammonium hydroxide. Yield 232 mg, 81%; HPLC (40/60) 2.57 minutes (98%); PBMS 416/418 (MH+, 100%);
