Product 1

HCID 86727670(3S)-1-[4-[5-[5-amino-6-(5-tert-butyl-1,3,4-oxadiazol-2-yl)pyrazin-2-yl]-1-methyl-1,2,4-triazol-3-yl]-1-piperidyl]-3-hydroxy-butan-1-oneYield 68.2%

Procedure

Using a similar procedure as Example 4, 3-(5-tert-butyl-1,3,4-oxadiazol-2-yl)-5-(1-methyl-3-(piperidin-4-yl)-1H-1,2,4-triazol-5-yl)pyrazin-2-amine was reacted with (S)-3-hydroxybutanoic acid to afford the title compound (167 mg, 68.2%) as a pale yellow solid. 1H NMR Spectrum: (CDCl3) 1.24 (3H, d), 1.52 (9H, s), 1.85 (2H, m), 2.10 (2H, m), 2.35 (1H, dd), 2.55 (1H, d), 2.90 (1H, m), 3.05 (1H, m), 3.20 (1H, m), 3.90 (1H, m), 4.25 (1H, m), 4.31 (3H, s), 4.6 (1H, m), 9.03 (1H, s); Mass Spectrum [M+H]+=470.
