(R)-3-[[N-(2-Amino-5-trifluoromethylbenzoyl)glycyl]amino]pyrrolidine (17.2 mg, 0.04 mmol) was dissolved in THF (1 mL), and 2,4-dimethoxy-5-pyrimidinecarboxaldehyde (6.7 mg, 0.04 mmol) was added to the resulting solution. Sodium triacetoxyborohydride (12.7 mg, 0.06 mmol) and glacial acetic acid (2.4 mg, 0.04 mmol) were subsequently added to the mixture. The resulting mixture was stirred at 50° C. for 24 hours and then concentrated. The residue was dissolved in dichloromethane (1 mL) and washed with a 1 M aqueous solution (1 mL) of NaOH. The organic layer was collected and concentrated, and a dichloromethane solution of 25% trifluoroacetic acid (1 mL) was added. The resulting mixture was stirred at room temperature for 1 hour and then concentrated. The obtained residue was purified by HPLC to thereby provide (R)-3-[[N-(2-amino-5-trifluoromethylbenzoyl)glycyl]amino]-1-(2,4-dimethoxypyrimidin-5-ylmethyl)pyrrolidine (Compd. No. 2175) (18.6 mg, 78%). The purity was determined by RPLC/MS (98%). ESI/MS m/e 483 (M++H, C21H25F3N6O4).
