Reaction Steps
To an ice water cooled solution of methyl [trans-4-(5-aminopyridin-2-yl)cyclohexyl]acetate hydrochloride, prepared as above, (831 mg, 2.59 mmol) in DCM (50 mL) was added triethylamine (1.3 mL, 9.31 mmol) followed by methyl chlorooxoacetate (0.31 mL, 3.36 mmol) and the reaction mixture was allowed to stir at O—C for 2 hrs. The reaction mixture was diluted with DCM (100 mL) and washed with water (80 mL) then brine (80 mL) and the aqueous layer was re extracted with DCM (50 mL). The organic washings were combined, dried and concentrated to give the title compound, 865 mg (2.59 mmol, 100%) which was taken through to the next stage; 1H NMR (CDCl3) δ 1.13-1.27 (m, 1H), 1.57-1.64 (m, 3H), 1.84-2.00 (m, 5H), 2.26 (d, 2H), 2.62-2.70 (m, 1H), 3.68 (s, 3H), 3.98 (s, 3H), 7.18 (d, 1H), 8.13 (d, 1H), 8.60 (s, 1H), 8.82 (brs, 1H); MS m/e MH+ 335.
