Participants

Reaction Steps

A solution of the product of Step 1 (0.350 g, 0.74 mmol) in dichloromethane (10 ml) and trifluoroacetic acid (5 ml) was stirred at room temperature for 3 hours. The solution was concentrated and the residue co-evaporated with dichloromethane. The residue was dissolved in water (10 ml) and the solution was neutralised with sodium carbonate solution. The solvent was evaporated in vacuo and the resulting solid was dried over phosphorus pentoxide to give title compound which was used in the next step; MS(AP+) m/e 374 [M+H]+.
