反応手順

1,1-Dimethylethyl[(6-cyclopropyl-4-methyl-2-oxo-1,2-dihydro-3-pyridinyl)methyl]carbamate (0.28 g, 1.006 mmol) was added to EtOAc (9 mL) and methanol (1.0 mL). The suspension was stirred at room temperature for 5 min., followed by addition of 4M HCl in dioxane (5.03 mL, 20.12 mmol), and the contents were stirred at room temperature overnight. The volatiles were then removed in vacuo to afford a solid. The solid was triturated with ether, filtered, and dried in a vacuum oven at 45° C. for 4 h. The title compound was collected as 0.22 g (100% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 0.78-0.86 (m, 2H), 0.95-1.03 (m, 2H), 1.83 (tt, J=8.46, 5.05 Hz, 1H), 2.16-2.22 (m, 3H), 3.75 (q, J=5.47 Hz, 2H), 5.79 (s, 1H), 8.02 (br. s., 3H), 11.92 (br. s., 1H).
