Reaction Steps

The title compound was prepared from 7-[(3R)-3-[(1,1-dimethylethoxycarbonyl)-amino]-4-(3,4-difluorophenyl)butanoyl]-3-ethyl-5,6,7,8-tetrahydro-1,2,4-triazolo[4,3-a]pyrazine (30 mg, 0.067 mmol from Step C), in 1.5 mL of methanol saturated with hydrogen chloride, using a procedure analogous to that described in Example 1, Step D. Evaporation of solvent afforded 28 mg of the title compound as a viscous oil. 1H NMR (500 MHz, CD3OD) δ 1.45 (t, 3H), 2.93-3.07 (m, 6H), 3.90-4.31 (m, 5H), 5.08 (m, 2H), 7.16 (s, 1H), 7.31 (m, 2H). ESI-MS 350 (M+H).
