Procedure
4-amino-1,7,7-trimethylbicyclo[2.2.1]heptan-2-one (8) (1.1 g, 5.29 mmol)) and 4,5-dichloro-3-nitropyridin-2-amine (1 g, 4.81 mmol) were taken in IPA (30 ml) and DIPEA (4.6 ml, 26.44 mmol)) was added to the reaction mixture which was then heated at 60° C. for 24 h when TLC confirmed completion of reaction. The reaction mixture was cooled to rt and concentrated in vacuuo. Pure product (9) (1.63 g, 92%) was obtained as a yellow solid after purification by column chromatography using silica gel (100-200 mesh). NMR: δ (1H, 400 MHz, CDCl3): 0.87 (3H, s), 0.97 (3H, s), 1.05 (3H, s), 1.44-1.54 (1H, m), 1.70-1.80 (1H, m), 1.90-2.20 (1H, m), 2.30-2.40 (1H, m), 2.47 (1H, dd, J=3.2, 18.0 Hz), 2.88 (1H, d, J=18.4 Hz), 6.55 (2H, s), 7.85 (1H, s), 7.96 (1H, s) LCMS: (254 nm): [M+H]+ 339.10 (86.27%)
