Procedure
DIPEA (0.11 mL) and O-(tetrahydro-2H-pyran-2-yl)hydroxylamine (24 mg) were added to a DMF (5.0 mL) solution of 1-{[2-carboxy-1-(methylamino)-1-oxopropan-2-yl](methyl)carbamoyl}-4-iodobenzene (Intermediate 11, 81 mg) and HATU (120 mg) under ice cooling, and the mixture was stirred for 2 hours at room temperature. Water was added, and the mixture was extracted with chloroform. Then, the organic layer was washed with brine, and dried over magnesium sulfate. The desiccant was filtered out, and then the solvent was distilled off under reduced pressure. The resulting residue was purified by NH type silica gel column chromatography (gradient elution with chloroform/methanol=100/0→95/5) to obtain 2-[(4-iodobenzoyl)(methyl)amino]-N,2-dimethyl-N′-(tetrahydro-2H-pyran-2-yloxy)propanediamide (Intermediate 12, light yellow oil) (59 mg, 57%).
