Reaction Steps

A solution of EXAMPLE 7F (500 mg), tert-butyl (1S,4S)-(−)-2,5-diazabicyclo(2.2.1)heptane-2-carboxylate (0.259 g), and diisopropylethylamine (0.622 mL) in acetonitrile (11.9 mL) was heated at 50° C. for 18 hours then cooled, diluted with dichloromethane, washed with saturated ammonium chloride and brine, and dried (MgSO4), filtered, and concentrated; and the concentrate was recrystallized from diethyl ether.
