Comments
Synthesis: Using this acid (HCl or TMS-Cl) catalysed method, a library of 60 compounds was synthesised. Optimisation (of solvent, acid catalyst, time, temperature and concentrations) was carried out to find the best yields and a method where the products would precipitate and be easily separated and isolated. Addition of the acid (in acetonitrile) to the reaction mixture was done automatically by the Synthesizer system.
Work-up and purification: After heating of the reaction mixture, 138 µl isopropanol was added and the mixture stirred for 10 s and heated once more, to 125°C for 30 s. After the second heating, the product hydrochloride was filtered off and washed twice with acetonitrile.
Characterisation: By LCMS, 1H and 13C NMR.
