Procedure
A similar procedure to that described for INTERMEDIATE 47 utilizing 2-(methylamino)ethanol (2.3 g, 30.62 mmol) as starting material was followed, with subsequent purification by column chromatography (ISCO, silica gel column, eluting with 60→100% EtOAc/hexanes for 14 minutes) to give the title product (5.96 g, yield: 93%).
Workup
- customwas followed, with subsequent purification by column chromatography (ISCO, silica gel column, eluting with 60→100% EtOAc/hexanes for 14 minutes)
