実験手順

To the compound from Step B (0.2 g, 0.64 mmol) was added methanolic ammonia (saturated at 0° C.; 40 mL). The mixture was heated in a stainless steel autoclave at 100° C. for 14 h, then cooled and evaporated in vacuo. The crude mixture was purified on a silica gel column (5×5 cm) with CH2Cl2/MeOH (50/1, 30/1, 20/1) gradient as eluent to give the title compound as a white solid (0.12 g).
