Participants

Reaction Steps

The solution of 1-(3'-benzyloxy-n-octyl)-4-ethoxycarbonyl-2-(ethoxycarbonylmethyl)-pyrrolidin-3,5-dione in ether (obtained as described above) was stirred overnight in the presence of magnesium sulphate. The mixture was filtered and the filtrate was evaporated in vacuo giving 1-(3'-benzyloxy-n-octyl)-2-(ethoxycarbonylmethyl)-pyrrolidin-3,5-dione [71 g., 95% overall yield for steps (b) and (c)] as a yellow oil.
