Reaction Steps

In a dry round bottomed flask was added 10% Pd/C (301.5 mg) and was wetted with 3–5 drops of water. Nitrogen was blown over the Pd/C for about 5 minutes, then methanol (10 mL) was added cautiously and nitrogen was blown on the mixture for another 5 minutes. Triazine E3 (251.8 mg, 0.50 mmol) dissolved in methanol (5 mL) was added followed by ammonium formate (381.5 mg, 6.0 mmol), and the reaction was stirred and heated reflux for about 1.5 hours. Methylene chloride was added and allowed to cool to room temperature. The mixture was filtered by vacuum through Celite with a methylene chloride rinsing and the filtrate was concentrated in vacuo. The material was purified by silica gel flash chromatography eluting with 90:9:1 by volume methylene chloride:methanol:ammonium hydroxide, and the collected fractions were dried over anhydrous magnesium sulfate, filtered and then concentrated in vacuo to give a light yellow solid (E4) (98 mg, 44%); mp 130° C.; HPLC: Inertsil ODS 3V C18, 40:30:30 [KH2PO4(0.01 M, pH 3.2):CH3OH:CH3CN], 264 nm, Rt 3.2 min, 99.6% purity; MS (TOF ES+) m/z 412 (M+H, 100), 235.6 (87.2), 206.6 (16.1).
