Procedure

4-(6-Cyano-4-(methoxycarbonyl)chroman-7-yloxy)benzoic acid (from Example 7, Step B) (12 mg, 0.034 mmol), HBTU (15 mg, 0.041 mmol) were diluted with N-methylpyrrolidone (1 mL) followed by the addition of 2-aminoindan (4.5 mg, 0.034 mmol), N,N-diisopropylethylamine (0.015 mL, 0.085 mmol) and DMAP (1.2 mg, 0.010 mmol). After stirring for 3 hours, the reaction was loaded directly onto a Biotage 12i cartridge eluting with 5% ethyl acetate/hexanes to 100% ethyl acetate to yield the title compound (12 mg, 75% yield).
