Reaction Steps

A solution of 4-[2-[2-(N-phenylmethoxycarbonylamino)ethyl]-4-phenyl-oxazol-5-yl]benzenesulfonamide (Step 1) (0.75 g, 1.6 mmol) in MeOH (15 mL) containing acetic acid (0.1 mL) was treated with 10% Pd on carbon (0.35 g) and stirred under an atmosphere of hydrogen at 50 psi at room temperature for 2.5 h. The catalyst was removed by filtration, and the filtrate was concentrated under reduced pressure to afford a white powder which was purified by reverse-phase HPLC using a gradient of 10–90% CH3CN in H2O to afford 0.55 g of 4-[2-(2-aminoethyl)-4-phenyloxazol-5-yl]benzenesulfonamide as its trifluoroacetate salt: 1H NMR (CD3OD/300 MHz) δ 7.91 (d, 2H, J=7.9 Hz), 7.74 (m, 2H,), 7.63 (m, 2H), 7.44 (m, 3H), 3.49 (t, 2H, J=6.6 Hz), 3.33 (t, 2H, J=6.6 Hz). FABMS m/z=344 (M+H). HRMS calcd for C17H18N3O5S 344.1069. Found 344.1048.
