The reaction was maintained at 65° C. for 18 hours. Solvent was removed by rotary evaporation under reduced pressure and furthermore with high vacuum distillation to yield brown oil. The oil was placed in a beaker and stirred with hexane/t-butylmethylether 1:1 solution (400 mL) causing a white precipitate. The solids were collected by vacuum filtration. Solids were dried in a vacuum oven at 30° C. overnight. Yield 305.0 grams (0.089 moles, 82%).
