Reaction Steps

The product from step (iii) above (0.15 g) was dissolved in pyridine (2 ml) and 3-methoxybenzoyl chloride (0.064 g) added. After 16 hours at room temperature, water and ethyl acetate were added, the organic phase separated, dried and concentrated to an oil. Purification by chromatography (dichloromethane:methanol, 95:5) gave an oil which was treated with 1.0M ethereal hydrogen chloride solution to give the titled product as a solid (0.043 g).
