Participants

Reaction Steps

To the amine from Step (b) (0.116 g, 0.3 mmol) in dry dichloromethane (5 ml) was added pyridine (0.060 ml, 0.75 mmol), followed by methanesulfonyl chloride (0.035 ml, 0.45 mmol), and the mixture was stirred at room temperature for 48 hours. After dilution with water (20 ml) and extraction with ethyl acetate (3×20 ml), the combined organic fractions were washed with brine, dried (MgSO4 and evaporated under reduced pressure. The residue was purified by flash chromatography eluting with 10% to 30% ethyl acetate in iso-hexane to give as a mixture of diastereoisomers the title compound as a colourless oil (35 mg, 25%).
