822-82-2, To a solution of l-[4-[ethyl(tetrahydropyran-4-yl)amino]-5-oxido-6,7-dihydro- thieno[3,2-d]pyrinnidin-5-iunn-2-yl]azetidin-3-ol (5.0 mg, 14 muiotatauiotaomicronIota) in DCE (0.2 mL) was added solutions of 4-isothiazolecarboxylic acid (2.7 mg in 0.2 mL DCE, 21 muiotatauiotaomicronIota), DMAP (0.52 mg in 0.1 mL DCE, 4.3 muiotatauiotaomicronIota) and EDAC (4.1 mg in 0.1 mL DCE, 21 muiotatauiotaomicronIota). The mixture was shaken at 50 C for 20 minutes before it was concentrated in vacuo. Prep HPLC purification (basic) afforded the title compound as colorless oil. 1H NMR (DMSO-d6) delta: 9.81 (s, 1H), 9.00 (s, 1H), 5.52 – 5.45 (m, 1H), 4.84 – 4.68 (m, 1H), 4.53 – 4.40 (m, 2H), 4.13 (dd, 2H), 3.97 (td, J = 11.2, 4.3 Hz, 2H), 3.71 – 3.56 (m, 2H), 3.51 – 3.43 (m, 1H), 3.43 – 3.34 (m, 2H), 3.25 – 3.18 (m, 1H), 3.07 – 2.97 (m, 2H), 1.95 – 1.82 (m, 2H), 1.75 (d, J = 12.3 Hz, 1H), 1.62 (d, 1H), 1.19 (t, J = 6.9 Hz, 3H). HPLC-Retention time (XE Metode 7 CM) : 1.95 minutes. Detected “M + l”-mass: 464.15.
