Benzylamine → N-benzyl-2-(tert-butoxycarbonylamino)-5-indan carboxamide

Participants

Reaction Steps

Using 2-(tert-butoxycarbonylamino)-5-carboxyindan (400 mg, 1.44 mmol), benzylamine (0.24 ml, 2.2 mmol), triethylamine (1.4 ml, 10 mmol), propanephosphonic acid anhydride (2.1 ml), dimethylaminopyridine (a catalytic amount) and methylene chloride (12 ml), a similar procedure to a) in Production Example 218 was carried out. The product obtained was purified by silica gel chromatography (methylene chloride:methanol=95:5) to obtain N-benzyl-2-(tert-butoxycarbonylamino)-5-indan carboxamide (460 mg, 1.25 mmol) having the following physical properties:
