Conditions: temp:0.00; pressure:0.00; stir:

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

Procedure: A solution of 1,3-propanesultone (9.4 g, 75 mmol) in 2-butanone (35 mL) was added dropwise to a the crude solution of 1-methyl-1-cyclopentylamine (mixture of solvent from previous step).

Conditions: temp:80.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Prepared according to Example 127, using DIPEA (141 μl, 0.803 mmol), 2-(3-fluoro-2-methylquinoxalin-5-yl)-6,7-dihydro-1H-pyrrolo[3,2-c]pyridin-4(5H)-one (Example 126; 40 mg, 0.135 mmol), 1-methylcyclopentanamine (40.2 mg, 0.405 mmol, Sigma Aldrich), and DMSO (1.4 mL) and stirring at 80° C. for 2 h. Purification by high throughput parallel purification (Rilas Technologies, Woburn, Mass.) provided 2-(2-methyl-3-(1-methylcyclopentyl)amino)-5-quinoxalinyl)-1,5,6,7-tetrahydro-4H-pyrrolo[3,2-c]pyridin-4-one. 1H NMR (DMSO-d6) δ: 12.21 (s, 1H), 7.83-7.91 (m, 1H), 7.53-7.61 (m, 1H), 7.30-7.39 (m, 1H), 7.07 (s, 1H), 6.95 (s, 1H), 6.18 (s, 1H), 3.40-3.48 (m, 2H), 2.85-2.94 (m, 2H), 2.55 (s, 3H), 2.37-2.48 (m, 2H), 1.67-1.85 (m, 6H), 1.64 (s, 3H). m/z (ESI, +ve) 376.1 (M+H)+.

Procedure: A solution of (R)-2-(tetrazolo[1,5-a]pyrid-6-yl)oxirane (375 mg, 2.31 mmol) and (1-methylcyclopentyl)amine (229 mg, 2.31 mmol) in 10 ml of absolute ethanol was heated at reflux for 20 hours. The reaction mixture was concentrated to dryness and the residue (532 mg) purified by preparative Tlc on silica gel (90:10:1 methylene chloride:methanol: NH4OH) to afford 375 mg of product. at reflux for 20 hours The reaction mixture was concentrated to dryness the residue (532 mg) purified by preparative Tlc on silica gel (90:10:1 methylene chloride:methanol: NH4OH)
