Procedure

Using 2-(tert-butoxycarbonylamino)-5-carboxyindan (30 mg, 0.11 mmol) synthesized in Reference Production Example 4, aniline (21 μl, 0.23 mmol), triethylamine (0.20 ml, 1.4 mmol), propanephosphonicacid anhydride (0.3 ml), dimethylaminopyridine (a catalytic amount) and methylene chloride (0.25 ml), a similar procedure to a) in Production Example 21 was carried out. The product obtained was purified by silica gel chromatography (hexane:ethyl acetate=4:1 to 7:3) to obtain N-phenyl-2-(tert-butoxycarbonylamino)-5-indan carboxamide (27 mg, 0.077 mmol) having the following physical properties:
