As the paragraph descriping shows that 25637-16-5 is playing an increasingly important role.

25637-16-5, 4-Bromotetrahydropyran is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

25637-16-5, Step 1: To a solution of Core B (700.00 mg, 2.84 mmol, 1.00 eq) in MeCN (14 mL) was added CS2CO3 (1.85 g, 5.68 mmol, 2.00 eq) at 0C. After 30 min, 4- 0242952445-01 bromotetrahydropyran (703.03 mg, 4.26 mmol, 1.50 eq) was added. The mixture was stirred at 100C for 16 h in a sealed tube. The reaction mixture was filtered and the filtrate was concentrated. The crude product was purified by prep-HPLC (TFA) to give compound 39_6 (45.0 mg, 136.18 mupiiotaomicron, 4.8% yield) as a yellow solid. LCMS: RT = 0.702 min, mlz 331.1 [M+H]+ NMR (CDCb, 400 MHz) delta 8.42-8.40 (d, / = 5.6 Hz, 1H), 7.94 (s, 1H), 7.11- 7.10 (d, / = 5.2 Hz, 1H), 4.37-4.33 (m, 1H), 4.19-4.15 (m, 1H), 3.59-3.54 (m, 2H), 3.28- 3.26 (d, / = 6.4 Hz, 2H), 2.6 (s, 3H), 2.44-2.40 (m, 2H), 1.87-1.84 (m, 2H), 1.05-1.02 (m, 1H), 0.55-0.50 (m, 2H), 0.33-0.30 (m, 2H).
