Procedure

A suspension of (±)-(E)-3-{1′-benzyl-3,4-dihydro-4-oxo-spiro[2H-(1,3)-benzoxazine-2,3′-piperidin]-6-yl}-acrylic acid (230 mg, 0.55 mmol) in DCM (6 ml) was treated with TEA (0.12 ml, 0.90 mmol) and then with EDC (172 mg, 0.900 mmol), HOBt (121 mg, 0.896 mmol) and NH2OTHP (84 mg, 0.72 mmol) following the procedure described in Example 30, Step B, giving (±)-(E)-3-{1′-benzyl-3,4-dihydro-4-oxo-spiro[2H-(1,3)-benzoxazine-2,3′-piperidin]-6-yl}-N-(tetrahydro-pyran-2-yloxy)-acrylamide (120 mg) as a light yellow solid.
