実験手順

A dichloromethane solution (1 mL) of 3-fluoro-5-(trifluoromethyl)benzoyl chloride (0.058 mmol) was added to a solution of (R)-1-(3,5-dimethylisoxazol-4-ylmethyl)-3-(glycylamino)pyrrolidine (0.050 mmol) and a piperidinomethylpolystyrene (58 mg) in chloroform (0.2 mL) and dichloromethane (0.75 ml). The reaction mixture was stirred at room temperature for 2 hours, and methanol (1.0 mL) was then added. The resulting mixture was stirred at room temperature for 10 hours. The reaction mixture was loaded onto a Varian™ SCX column and washed with methanol (16 mL). The obtained crude product was eluted with a solution of 2 M NH3 in methanol (6 mL) and concentrated to provide (R)-3-[N-[3-fluoro-5-(trifluoromethyl)benzoyl]glycyl]amino-1-(3,5-dimethylisoxazol-4-ylmethyl)pyrrolidine (Compd. No. 1191) (19.5 mg, 88%). The purity was determined by RPLC/MS (100%). ESI/MS m/e 443.2 (M++H, C20H22F4N4O3).
