実験手順
(S)-2-Amino-3-phenyl-1-thiazolidin-3-yl-propan-1-one hydrochloride (2.6 mmol) and 5-chloro-1H-indole-2-carboxylic acid (2.6 mmol) were coupled according to Procedure A (0-25° C. reaction temperature, 96 hour reaction time, washed with acid first then base). The crude product was triturated with 1:1 ether-hexanes and dried. Yield 966 mg, 91%; HPLC (60/40) 7.99 minutes (97%); PBMS 414/416 (MH+, 100%);
