Participants

Reaction Steps

Using a procedure similar to that described in Example 1c, 8 g (40 millimoles) of (2,3-dihydro-1,1,2,3,3-pentamethyl-5(1H)-indenyl)-ethyne and 4.6 g (25 millimoles) of 4-bromobenzaldehyde were reacted, the solution was filtered and the filtrate was evaporated down to give a residue, which was extracted with sodium bicarbonate solution/methylene chloride. Stirring the residue with methylene chloride and a little cyclohexane gave 2.3 g (29%) of the title compound of melting point 106°-107° C.
