실험 절차

The title compound (4.1 g, yield: 49%) was prepared using a procedure similar to the one described for the synthesis of INTERMEDIATE 23 utilizing 2-(methylamino)ethanol (2.0 g, 26.6 mmol) as starting material. The title product was purified by column chromatography (ISCO, 40 g silica gel column, eluting with 0→100% DCM/10% MeOH in DCM with 1% NH4OH).
