実験手順
N-(5-Benzyloxy-4-oxo-4H-pyran-2-ylmethyl)-3-methyl-benzenesulfonamide (7-04) (24.0 g, 57.60%) was synthesized as a light brown solid from 2-aminomethyl-5-benzyloxy-pyran-4-one (5) and 3-methyl-benzenesulfonyl chloride (6-04) (24.67 g, 129.87 mmol) following the procedure described for N-(5-benzyloxy-4-oxo-4H-pyran-2-ylmethyl)-benzenesulfonamide (7-01).
