Here is a downstream synthesis route of the compound 18385-82-5.
[0332j A solution of 7-bromochroman-4-ol (200 mg, 0.88 mmol, 1.0 equiv) in toluene (5 mL) was cooled in an ice bath under N2 and treated with DPPA (532 mg, 1.93 mmol, 2.2 equiv) in one portion followed by DBU (293 mg, 1.93 mmol, 2.2 equiv). The reaction temperature was kept at 0 C for 1 h and then was warmed to room temperature for 16 h. The mixture was diluted with EtOAc (50 mL), washed with 2N HC1 (2 x 30 mL), brine and the organic layer was dried over Na2504, filtered then concentrated. The crude product was purified by silica gel column (eluted with PE). 4-azido-7-bromochroman (188 mg, yield: 90%) was obtained as a white solid. ?H NMR (400 MHz, CDC13) 5: 7.07-7.06 (m, 3H), 4.56 (t, J= 3.6 Hz, 1H), 4.30-4.17 (m, 2H), 2.19-1.99 (m, 2H).
