実験手順
The title compound (0.14 g, 32%) was prepared as a gummy liquid from 2-(2,3-dihydro-1,4-benzoxazin-4-yl)ethyl methanesulfonate (0.36 g, 1.42 mmol), potassium carbonate (0.80 g, 5.8 mmol) and ethyl 2-hydroxy-3-(4-hydroxyphenyl)propanoate (0.3 g, 1.42 mmol) using conditions analogous to that described in preparation 2.
