Procedure
The product of step A (510 mg, 1.16 mmol) was dissolved in ethanol (50 mL) and sodium hydroxide (6.5 mL of a 1N solution, 6.5 mmol) added. The solution was heated at reflux for 1.5 hours, diluted with water (45 mL), and the ethanol removed under vacuum. The solution was acidified to pH=3 with 1N HCl (˜7 mL) with stirring. The resulting solids were filtered, washed with water, and dried under vacuum to afford the product (308 mg, 89%). LRMS (ES): 298.1 ([M+H]+. HRMS: Calculated for C15H16N5O2: 298.1304; Found: 298.1320. 1HNMR (600.1343 MHz, CDCl3): 12.5 (b, H), 8.42 (s, 1H), 8.26 (d, 2H), 8.19 (s, 1H), 7.90 (d, 1H), 7.67, (d, 1H), 7.45 (m, 1H), 6.58 (s, 1H), 4.50 (t, 2H), 3.29 (m, 2H), 2.13 (t, 2H).
