Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: The title compound was prepared using standard chemical manipulations and procedures similar to those used for the preparation of 4-(1-(4-cyclobutyl-2-methyl-5-(5-methyl-4H-1,2,4-triazol-3-yl)benzoyl)piperidin-4-yl)benzonitrile (compound 152), using (S)-tetrahydrofuran-2-carbohydrazide (compound 172.1) in place of acetohydrazide. m/z (ES+) 496 (M+H)+.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a round-bottom flask was added a solution of (S)-tetrahydrofuran-2-carboxylic acid (3.00 g, 25.8 mmol, 1.00 equiv) in dichloromethane (40 mL). EDC.HCl (7.50 g, 39.1 mmol, 1.50 equiv), HOBT (5.20 g, 38.5 mmol, 1.50 equiv), and hydrazine hydrate (2 mL, 2.00 equiv, 99%) were added to the reaction. The resulting solution was stirred overnight at room temperature. The solids were removed by filtration and the filtrate was concentrated in vacuo to furnish 5.38 g (80%) of the title compound as a yellow oil. The solids were removed by filtration the filtrate was concentrated in vacuo

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: The title compound was prepared using standard chemical manipulations and procedures similar to those used for the preparation of 4-(1-(2,4-dimethyl-5-(5-((tetrahydrofuran-3-yl)methyl)-4H-1,2,4-triazol-3-yl)benzoyl)piperidin-4-yl)benzonitrile (compound 130), using (S)-tetrahydrofuran-2-carbohydrazide (compound 136.1) instead of 2-(tetrahydrofuran-3-yl)acetohydrazide (compound 130.4). m/z (ES+) 456 (M+H)+.

Conditions: temp:25.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a round-bottom flask was added a solution of (S)-tetrahydrofuran-2-carboxylic acid (3.00 g, 23.3 mmol, 1.00 equiv, 90%) in dichloromethane (40 mL). NH2NH2 (2 mL, 2.00 equiv), HOBt (5.20 g, 38.5 mmol, 1.50 equiv), and EDCI (7.50 g, 39.1 mmol, 1.50 equiv) were added and the resulting mixture was stirred overnight at 25° C. The solids were removed by filtration, and the filtrate was concentrated in vacuo to furnish 2.50 g (74%) of (S)-tetrahydrofuran-2-carbohydrazide as a yellow oil. The solids were removed by filtration the filtrate was concentrated in vacuo
