Versuchsvorschrift
The procedure of Example 1 was followed using N-phenyldiethanolamine (15.2 g, 83.9 mmol), triethylamine (24.0 mL, 167.8 mmol), dry THF (600 mL) and triphosgene (8.3 g, 28.8 mmol). The filtrate was concentrated yielding a clear oil containing a mixture of products. The product was purified using a column chromatography EtOAc:Hexanes (3:1) yielding 3.3 g (19%) of a clear oil which turned brown over time.
