Procedure

The product from Step F (4.373 grams), dissolved in 1,2-dichlorobenzene (45 mL) was refluxed under nitrogen for 8.5 hours. The solution was cooled to approx. 50° C. High vacuum was applied and the solvent removed until the residue solidified. The solid was dissolved in CH2Cl2 (100 mL), recovered, re-evaporated and chromatographed over silica gel (CH2Cl2). Evaporation of the appropriate fractions gave the title compound as a pale yellow solid.
