Procedure

Sodium hydride (32.5 g, 60% dispersion in oil) and N,N-dimethylformamide (DMF) (700 ml) were stirred under nitrogen at room temperature and a solution of the product from step (e) (178.1 g) in DMF was added dropwise. After 2 hours stirring at room temperature, a solution of butyl iodide (149.5 g) in DMF was added dropwise and the reaction left stirring for a further 2 hours. The reaction was poured into an ice cold mixture of water (560 ml), diethyl ether (300 ml) and ammonium chloride (120 g). The resulting organic layer was dried over potassium carbonate then concentrated to give the desired product as a brown oil (220 g).
