Procedure

Sitagliptin free base (0.5 gms) and ferulic acid (0.25 gms) were dissolved in methanol (3 ml) at 60° C. to 65° C. and the solution was cooled to room temperature. Isopropyl ether (25 ml) was added to the clear solution and stirred for 2 hours. Filtered the precipitated solids and allowed for suck dry for 30 minutes to obtain the title compound. Yield: 0.42 gms.
