Reaction Steps

A solution of the product from step b) (12.2 g, 48.0 mmol) in decalin (145 ml) was treated with trimethylorthoacetate (24.5 ml, 192 mmol) and hexanoic acid (0.61 ml). The flask was equipped with a vigreux column and heated to 180° C. Additional hexanoic acid (3 ml) was periodically added over 6 hours and the reaction was heated overnight. The reaction was concentrated on the rotavap and the residue was extracted with MeOH(100 ml ×2). The MeOH extracts were concentrated and purified by silica gel chromatography (EtOAc/Hexane-gradient) providing 4.36 g (29%) of the subtitle compound. MS: ESI (positive): 311, 313 (M+H).
