Reaction Steps

A solution of 1,1-dimethylethyl [(6-cyclobutyl-4-methyl-2-oxo-1,2-dihydro-3pyridinyl)methyl]carbamate (2.1 g, 7.2 mmol) in 4 N HCl (in 15 mL 1,4 dioxane) was heated to 60° C. for 1 h. The mixture was cooled to room temperature. The mixture was filtered and dried to give 3-(aminomethyl)-6-cyclobutyl-4-methyl-2(1H)-pyridinone as an HCl salt (1.95 g, 90%). LCMS MH+=193.1 1H NMR (400 MHz, DMSO-d6) δ 11.70 (br s, 1H), 8.01 (s, 3H), 6.04 (s, 1H), 3.74 (d, 2H), 3.32-3.39 (m, 1H), 2.22 (s, 3H), 2.17-2.20 (m, 2H), 2.06-2.11 (m, 2H), 1.85-1.95 (m, 1H), 1.71-1.79 (m, 1H).
