Methyl iodide (1.20 mL, 19.3 mmol) was added and the mixture was stirred overnight at RT. Diluted the mixture with EtOAc and extracted with aqueous sodium bicarbonate and water. Dried the organic layers over sodium sulfate, filtered, concentrated and purified by silica gel chromatography (10-15% MTBE/hexanes). Concentrated the product fractions to yield the title compound.
