実験手順

Methanolic methylamine solution (20% v/v, 6 mL) was added to a solution of Example 102 (0.330 g, 0.69 mmol) in methanol (2 mL) in an atmosphere of nitrogen and sealed in a pressure reactor vessel at 100° C. for 6 h. It was brought to room temperature, flushed with N2 gas, treated with chilled water and dilute HCl to neutral pH. The solid that precipitated was filtered, washed with water, dried and purified using flash chromatography (silica gel, MeOH/CHCl3) to obtain the title compound as an off white solid. Yield: 0.260 g (86.37%). 1H NMR (DMSO-d6): δ 2.40 (s, 3H, CH3), 2.70 (s, 3H, CH3), 2.72-2.75 (m, 4H, 2CH2), 3.30-3.35 (m, 4H, 2CH2), 5.10 (s, 2H, CH2), 7.10 (s, 1H, Ar), 7.20 (s, 1H, Ar), 8.10 (s, 1H, Ar) and 8.25 (s, 1H, Ar); MS: m/e (ES+) 436 (M+1).
