✦ Synopsis
XI SO.
( 2 0 m L ) was condensed at -190°C into a pressure flask containing l.Og (6.8 mmol) of 1 and I.0g (3.4mmol) of 3. The colorless solution was allowed to warm up in the dark to room temperature and stirred for 18 h. The moderately soluble precipitate that formed was filtered off and the soI\rnt was removed from the filtrate in vacuum. The residue was recrystallized from SO?, affording 1.6 g (79%) of 4 as pale yellow crystals. m.p
