The present invention provides a process for the preparation of 4-fluoro-2- methylbenzonitrile of Formula (II), and its use for the preparation of trelagliptin or its salts. The present invention provides an efficient, simple, and commercially friendly process for the preparation of 4-fluoro-2-methylbenzonitrile, which is used as an intermediate for the preparation of trelagliptin or its salts. The present invention avoids the use of toxic and hazardous reagents, high boiling solvents, and bromo intermediates such as 2-bromo-5-fluorotoluene, which is lachrymatory in nature and thus difficult to handle at a commercial scale.

Trelagliptin is a dipeptidyl peptidase IV (DPP-IV) inhibitor, chemically designated as 2- [[6-[(3i?)-3 -aminopiperidin- 1 -yl] -3 -methyl -2,4-dioxopyrimidin- 1 -yljmethyl] -4-fluorobenzonitrile, represented by Formula I.
Formula I
Trelagliptin is administered as a succinate salt of Formula la, chemically designated as 2-[[6-[(3i?)-3-aminopiperidin-l-yl]-3-methyl-2,4-dioxopyrimidin-l-yl]methyl]-4-fluorobenzonitrile butanedioic acid (1 : 1).
Formula la
U.S. Patent Nos. 7,795,428, 8,288,539, and 8,222,411 provide a process for the preparation of 4-fluoro-2-methylbenzonitrile by reacting 2-bromo-5-fluorotoluene with copper (I) cyanide in N,N-dimethylformamide.
Chinese Patent No. CN 102964196 provides a process for the preparation of 4-fluoro-2-methylbenzonitrile by reacting 4-fluoro-2-methylbenzyl alcohol with cuprous iodide in the presence of 2,2′-bipyridine and 2,2,6,6-tetramethylpiperidine oxide (TEMPO) in an anhydrous ethanol.
Copper (I) cyanide is toxic to humans, and therefore its use in the manufacture of a drug substance is not advisable. In addition, 2-bromo-5-fluorotoluene is converted to 4-fluoro-2-methylbenzonitrile by refluxing in N,N-dimethylformamide at 152°C to 155°C for 24 hours. This leads to some charring, resulting in a tedious work-up process and low yield. Furthermore, the use of reagents like cuprous iodide, 2,2′-bipyridine, and 2,2,6,6-tetramethylpiperidine oxide (TEMPO) is hazardous and/or environmentally-unfriendly, and therefore their use in the manufacture of a drug substance is not desirable.
The present invention provides an efficient, simple, and commercially friendly process for the preparation of 4-fluoro-2-methylbenzonitrile, which is used as an intermediate for the preparation of trelagliptin or its salts. The present invention avoids the use of toxic and hazardous reagents, high boiling solvents, and bromo intermediates such as 2-bromo-5-fluorotoluene, which is lachrymatory in nature and thus difficult to handle at a commercial scale.
