Compound (3) (22.82 g, 84.5 mmol) was dissolved in chloroform (100 ml), and 16 g (94 mmol) of m-chloroperbenzoic acid (mCPBA) was addedin small portions at RT over a period of 30 min. The mixture was stirred for an additional 2 h and after a negative TLC test for the starting material it was worked up by partitioning between sat. sodium hydrogen carbonate and chloroform. The combined chloroform extracts (3×200 ml) were evaporated yielding a light yellow solid material that was TLC pure.
