摘要

The position of the benzenesulfonyl grouping was established by mass spectrometry. In addition to the molecular peak at 300, ions were found having m/z 236 (M--SO2), 193 (236-- HNCO). The presence of the latter ion, and the absence of an ion with m/z 213, showed that the 4-methoxybenzenesulfonyl group is located in the 1-position of (Ia).
