Reaction Steps
A solution of the product from Step 2 (0.075 g, 0.17 mmol) in dichoromethane (1 ml) was treated with trifluoroacetic acid (1 ml). After 2 hours the reaction was reduced in vacuo, dissolved in methanol and applied to a SCX ion exchange column and eluted with methanol and then a mixture of methanol/0.880 ammonia (9:1). The basic fractions were then reduced to afford the title compound, (0.053 g, 91%); MS (ES+) m/e 343 [M+H]+.
