Potassium Carbonate → tert-butyl 3-(4-[3-(acetylamino)phenyl]-3,6-dihydro-1(2H)-pyridinyl)propylcarbamate

Participants

Reaction Steps

A solution of N1-[3-(1,2,3,6-tetrahydro-4-pyridinyl) phenyl]acetamide hydrochloride (8.24 mmol), tert-butyl N-(3-bromopropyl)carbamate and potassium carbonate (33 mmol) in dry dioxane (30 mL) was heated at reflux temperature overnight. The solids were removed by filtration, the solution was concentrated in vacuo and the product was chromatographed, giving the desired product (110 mg). 1H NMR δ 7.65 (s, 1 H), 6.98 (s, 1 H), 7.45 (d, 1 H, J=7.8 Hz), 7.16 (apparent t, 1 H, J=7.8 Hz), 7.10 (d, 1 H, J=7.8 Hz), 6.02 (s, 1 H), 5.23 (b, 1 H), 3.40 (b, 2 H), 3.30-1.80 (m, 10 H), 2.18 (s, 3 H), 1.45 (s, 9 H)
