Participants

Reaction Steps

To a stirred solution of 2-bromo indanone and 5 g. of p-chloro-benzaldehyde in 20 ml of methanol under nitrogen is added at 5° to 10°C a solution of sodium methoxide in methanol (prepared by dissolving 1.15 g. of sodium in 50 ml of methanol). After 2 hours, 3'-(p-chlorophenyl)-spiro[indan-2,2'-oxirane]-1-one precipitates and is filtered off and recrystallized from methanol.
