Procedure

The title compound was prepared as the trifluoroacetate salt from 3-benzyloxy-5-(4-fluorobenzyl)-N-[(2-morpholin-4-yl)ethyl]-4-oxo-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrazine-2-carboxamide using a hydrogenation procedure similar to that found in Example 1, Step 5, except that the reaction time totaled 40 minutes. 1H NMR (400 MHz, CD3OD) δ 7.41-7.38 (m, 2H), 7.12-7.07 (m, 2H), 5.49 (s, 2H), 4.72 (br s, 2H), 4.28 (br s, 2H), 3.90 (br s, 6H), 3.75-3.71 (m, 6H); ES MS (M+1)=418.
