Reaction Steps

4-((S)-2-Azido-1-phenyl-ethylamino)-quinazoline-8-carboxylic acid amide ((0.28 g, 0.84 mmol) and palladium on carbon (5%, wet type, 56 mg) were combined in ethanol (5 mL) and chloroform (1 mL) and stirred under an atmosphere of hydrogen for 48 hours. The solution was filtered, rinsed with methanol and the solvent removed under reduced pressure. The sample was redissolved in THF/methanol and hydrogen chloride (4M solution in dioxane, 1 mL) was added. The solid formed was collected by filtration and purified by recrystallization from methanol/ethyl acetate (131 mg, 51%). 1H NMR (400 MHz, DMSO-d6) δ ppm 3.27-3.40 (m, 1 H) 3.84-3.98 (m, 1 H) 5.99 (br. s., 1 H) 7.29-7.36 (m, 1 H) 7.39 (t, J=7.39 Hz, 2 H) 7.60 (d, J=7.32 Hz, 2 H) 7.88 (s, 1 H) 8.16 (br. s., 1 H) 8.43 (br. s., 3 H) 8.59 (d, J=0.83 Hz, 1 H) 8.80 (s, 1 H) 9.29 (br. s., 1 H).
