A solution of 7,7-dimethyl-N-(tetrahydro-2H-pyran-2-yloxy)-4,5,6,7-tetrahydrothieno[3,2-c]pyridine-2-carboxamide (31 mg, 0.1 mmol) and triethylamine (41.8 μL, 0.3 mmol) in 1,2-dichloroethane (1 mL) was added (S)-1-phenylethyl isocyanate (22.1 mg, 0.15 mmol). The reaction was stirred at room temperature overnight. The solution was evaporated to dryness and the residue obtained was redissolved in tetrahydrofuran (1 mL). 4.0 M of hydrochloric acid in 1,4-dioxane (1 mL, 4 mmol) was added and the reaction solution was stirred at room temperature for 2 hours. The solution was evaporated to dryness, redissolved in DMSO (1 mL) and purified on an Agilent 1100 LC/MSD instrument to afford the title compound (17.8 mg, 46%). LCMS (FA) ES+ 374; 1H NMR (400 MHz, MeOD) δ 7.35-7.24 (m, 5H), 7.20-7.15 (m, 1H), 5.01-4.91 (m, 1H), 4.50 (d, J=4.0 Hz, 2H), 3.50 (d, J=4.6 Hz, 2H), 1.47 (d, J=7.1 Hz, 3H), 1.30 (s, 6H).
