Procedure
Method 1 was followed using 4-chloro-3-nitrophenyl cyclopropyl ketone (1.0 eq), 3-(N-Boc-amino)piperidine (1.2 eq), and TEA (1.5 eq) at 55° C. for 48 hours yielding tert-butyl 1-(4-(cyclopropanecarbonyl)-2-nitrophenyl)piperidin-3-ylcarbamate (96%). LCMS (m/z): 390.1 (MH+); LC Rt=3.28 min.
