I'm strugglin' with this synthesis problem. What's mostly tripping me up is the single methyl group alongside the alcohol group. I was thinking that there'd be a ketone in that position previously, which I could do a Grignard reaction with, which would give those two groups, but I can't figure out how to get to that from the starting alcohol.

Right now I figure PCC to get an aldehyde and then slapping aldehydes together until I have the 6 C's, and then somehow getting to the final product.

What is the product of the aldol condensation of 2 acetaldehydes?
