Reaction Steps

To a solution of the product from Step B (0.14 g, 0.55 mmol) in ethanol (10 mL) was added Pd/C (10%, 0.01 g) under a nitrogen atmosphere at room temperature. The resultant suspension was stirred for 18 h under a hydrogen atmosphere. The reaction was filtered through a filter aide and the filtrate was concentrated in vacuo to give a solid (0.09 g, 75%): mp 170-172° C.; MS (ES) m/z 219 (M+); 1H NMR (DMSO-d6) 8.25 (1H, s), 8.12 (1H, s), 8.04 (1H, br s), 7.80 (1H, d, J=8.0 Hz), 7.63 (1H, d, J=8.0 Hz), 7.44 (1H, s), 4.27 (2H, m), 3.34 (1H, m), 0.96 (3H, d, J=6.0 Hz). Analysis. Calculated for C11H14N4O: C, 60.53; H, 6.47; N, 25.67. Found: C, 60.37; H, 6.33; N, 25.48.
