Reaction Steps

To a light orange solution of (7-((benzyloxy)methyl)-3-(4-methoxybenzyl)-2-oxo-1-oxa-3-azaspiro[4.5]decan-7-yl)methyl methanesulfonate (5.71 g, 11.3 mmol) in DMSO (45.4 mL) was added sodium azide (2.21 g, 34.0 mmol). The reaction was heated at 120° C. behind a blast shield. After 4 days the reaction was cooled to RT and diluted with 1:1 EtOAc:Et2O (150 mL). This mixture was washed with water (3×100 mL), and the resulting organic layer was dried over magnesium sulphate, filtered, and concentrated to provide 7-(azidomethyl)-3-{[4-(methyloxy)phenyl]methyl}-7-{[(phenylmethyl)oxy]methyl}-1-oxa-3-azaspiro[4.5]decan-2-one (4.78 g, 89% crude yield) which was used without further purification. MS (m/z) 451.0 (M+H+).
