Procedure

A solution of EXAMPLE 1A (0.07 g, 0.3 mmol) and cyclopropylamine (0.33 mL, 4.8 mmol) in methanol (1 mL) was treated with sodium cyanoborohydride (0.016 g, 0.3 mmol) and acetic acid (0.2 mL). The mixture was stirred at ambient temperature for 48 hours and concentrated. The residue was purified by chromatography on silica gel column with 0-10% dichloromethane/methanol/0.1% ammonium hydroxide to provide the title compound. 1H NMR (DMSO-d6) δ 9.12 (s, 2H), 8.33 (d, J=8.3 Hz, 2H), 7.88 (d, J=7.4 Hz, 1H), 7.71-7.78 (m, 4H), 7.37 (t, J=7.8 Hz, 1H), 4.59 (m, 1H), 2.57 (s, 1 Hz), 1.64 (d, J=6.6 Hz, 3H), 0.81-0.87 (m, 1H), 0.75-0.79 (m, 1H), 0.66-0.72 (m, 2H).
