Procedure

To a stirring solution of 8a in dichloromethane (0.1 M) at 0° C. under nitrogen was added triethylamine (3.5 eq) and acetyl chloride (1.1 eq). The reaction was stirred at room temperature overnight. The reaction mixture was washed with saturated sodium bicarbonate (1×), brine (1×), dried over sodium sulfate, filtered, concentrated in vacuo and purified by flash chromatography using the ISCO (0-15% gradient methanol/dichloromethane) to afford the product.
