Procedure

Prepared according to the procedure for N-[(1S,2S)-2-{ [3-cyclopropyl-5-(trifluoromethyl)pyrazin-2-yl]amino}cyclopentyl]-2-(2H-1,2,3-triazol-2-yl)benzamide (Example 109) from N-[(1S,2S)-2-{[3-chloro-5-(trifluoromethyl)pyrazin-2-yl]amino}cyclopentyl]-2-(2H-1,2,3-triazol-2-yl)benzamide (Intermediate 29; 170 mg, 0.38 mmol) and 2-ethenyl-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS number 75927-49-0; 174 mg, 1.13 mmol) except this was then dissolved in methanol (1.4 ml) and to this was then added palladium on carbon (10% wt, 50% wet) (15 mg, 0.014 mmol) and the resulting mixture was stirred under a balloon of hydrogen gas for 2 hours. The reaction was filtered through diatomaceous earth (commercially sold under the trade mark “Celite”) and concentrated in vacuo to afford the title compound.
