An elementary termolecular reaction involves the simultaneous collision of three atoms, 37441-50-2, molecules, or ions. Here is a downstream synthesis route of the compound 37441-50-2, name is :1,2-Thiazinane 1,1-dioxide
solution of 2-(3-chloro-4-fluorobenzyl)-8-ethyl-4-fluoro-10-methoxy-6-methyl-7,8- dihydropyrazino[l’,2′: 1,5]pyrrolo[2,3-d]pyridazine-1,9(2H,6H)-dione (0.10 g, 0.23 mmol; Example 139), 1,2-thiazinane 1,1-dioxide (45 mg, 0.33 mmol), and cesium carbonate (0.15 g, 0.46 mmol) in anhydrous DMSO (9.5 mL) was heated in an oil bath at 50 C for 5 hours. The product mixture was filtered through a pad of Celite and the filtrate was subjected to purification on reverse phase preparative HPLC purification. Collection and lyophilization of appropriate fractions afforded the title material. Analytical HPLC indicated that the product is a 1:1 mixture of two isomers that arose from the relative stereochemistry of the 6-methyl group and restricted rotation between the sultam ring and the tricyclic core. ?H NMR (400 MHz, CDCI3) No. 7.48 (m 1H), 7.28 (m, 1H), 7.11 (t, J = 8.5 Hz, 1H), 5.17 (d, J = 14.2 Hz, ?H), 5.34 (in, 1/2 H), 5.29 (d, J = 14.2 Hz, (at)H), 5.23 (d, J = 14.2 Hz, ?H), 5.09 (d, J = 14.2 Hz, ?H), 5.07 (m, ?H), 4.18 (s, 1.5H), 4.16 (s, 1.5H), 4.12-3.17 (m), 2.58-2.00 (m), 1.57 (d, J = 6.6 Hz, 1.5H), 1.42 (d, J = 6.8 Hz, 1.5H), 1.23 (t, J = 6.8 Hz, 1.5H), 1.22 (t, J = 7.1 Hz, 1.5H). ES MS M+1 = 552
