실험 절차

By a similar reaction operation as in Starting Material Synthetic Example 4 using 4-aminochromane-7-carboxylic acid methyl ester (1.4 g) and benzyloxycarbonyl chloride (2.0 ml), the objective 4-(benzyloxycarbonylamino)chromane-7-carboxylic acid methyl ester (1.9 g) was obtained as colorless crystals.
