Reaction Steps

500 mg (2.11 mmol) of tert-butyl 3-aminopiperidine-1-carboxylate, 772 mg (4.22 mmol) of 2-amino-6-chloro-3-nitropyridine and 1.05 ml (6.34 mmol) of diisopropylethylamine were suspended in 18 ml of DMSO and heated in a microwave reactor at 120° C. for 45 min. The reaction mixture was purified by preparative reverse-phase HPLC. This gave 600 mg (81% of theory) of the product as a solid.
