試薬・触媒・溶媒 1

HCID 3776Isopropanol溶媒

実験手順

A solution of 15.4 g of benzyl [4-(2,3-epoxypropoxy)phenyl]ether and 17.0 g of 6-(2-benzylaminopropoxy)-2,3-dihydro-2,2-dimethyl-4H-1,3-benzoxazin-4-one in 100 ml of isopropanol is refluxed for 24 hours, filtered and concentrated by evaporation. Trituration of the residue with approximately 200 ml of ether results in crystallisation of 1-[N-[2-(2,3-dihydro-2,2-dimethyl-4-oxo-4H-1,3-benzoxazin-6-yloxy)-1-methylethyl]benzylamino]-3-(4-benzyloxyphenoxy)propan-2-ol having a melting point of 149°-160° (in which the enantiomer pair A is present in greater amount).
