Reaction Steps

A solution of 1,1-dimethylethyl {[4-methyl-2-oxo-6-(phenylmethyl)-1,2-dihydro-3-pyridinyl]methyl}carbamate (1.2 g, 3.66 mmol) in 4N 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)-4-methyl-6-(phenylmethyl)-2(1H)-pyridinone as an HCl salt (0.725 g, 87%). LCMS MH+=229.1 1H NMR (400 MHz, DMSO-d6) δ 11.9-12.0 (br s, 1H), 7.99 (br s, 3H), 7.20 (s, 5H), 5.97 (s, 1H), 3.72-3.75 (m, 4H), 2.17 (s, 3H).
