Reaction Steps

A similar procedure to that described for INTERMEDIATE 48 utilizing benzyl 2-hydroxyethyl(methyl)carbamate (INTERMEDIATE 51, 0.46 g, 2.20 mmol) as starting material was followed, with subsequent purification by column chromatography (ISCO, 12 g silica gel column, eluting with 0→100% EtOAc/hexanes) to give the title product (590 mg, yield: 67%).
