Participants

Reaction Steps

The compound (0.35 g, 0.53 mmol) obtained in Example 21 was dissolved in dichloromethane (5 ml). To the solution was added 1M hydrogen chloride in ether (1.06 ml, 1.06 mmol) under ice-cooling. The mixture was stirred for 30 minutes, the solvent was distilled off under reduced pressure. Thus obtained residue was recrystallized from dichloromethane-n-hexane to give pale yellow crystals (0.30 g, 77%).
