HCID 3776IsopropanolSolvent

Procedure

Sitagliptin free base (0.25 gms) and coumaric acid (0.10 gms) were dissolved in Isopropanol (4 ml) at 60° C. to 65° C. and the resultant solution left for slow solvent evaporation at room temperature for 48 hours. Precipitated solids were filtered and dried at 50° C. to 55° C. for 4 hours to obtain the title compound. Yield: 0.14 gms.
