실험 절차

A mixture of EXAMPLE 110A (1.9 g) in dichloromethane (3 mL) was treated with 1M titanium(IV) chloride in dichloromethane (9.06 mL), cooled to 0° C., treated with tert-butyl piperazine-1-carboxylate (3.07 g), stirred at ambient temperature for 3 hours, treated with NaCNBH3 (0.828 g) in methanol (5 ml), stirred at room temperature overnight, neutralized with aqueous NaOH and concentrated. The concentrate was treated with ethyl acetate and filtered. The organic filtrate was washed with water and concentrated. The concentrate was dissolved in methanol/trifluoroacetic acid/dimethylsulfoxide, loaded onto a reverse phase C18 column and eluted with 0-80% acetonitrile in 0.1% trifluoroacetic acid water over 70 minutes.
