Procedure

(R)-4-(4-chlorobenzyl)-3-methyl-5-(pyrrolidin-2-yl)-4H-1,2,4-triazole hydrochloride (50 mg, 0.8 mmol) was dissolved in dichloromethane (2 ml). HATU (75 mg, 0.19 mmol), (α,α,α-trifluoro-p-tolyl)acetic acid (37 mg, 0.18 mmol) and N,N-diisopropylethylamine (0.078 ml, 0.45 mmol) were added while stirring. The reaction mixture was stirred for 12 h then evaporated to dryness. Residue was taken up in EtOAc (20 ml) and washed with saturated solutions of NaHCO3 and NaCl. Organics were dried (NaSO4), filtered and concentrated. Purification by HPLC (water/acetonitrile gradient, 20% to 100% acetonitrile with 0.1% TFA) afforded the desired product as a white amorphous solid (76.3 mg, 91%).
