1,1'-Carbonyldiimidazole → HCID 12041757, compound

Participants

Reaction Steps

To a solution of (7,8-diamino-chroman-2-yl)-methanol (194 mg, 1 mmol) in THF (50 mL) was added 1,1′-carbonyldiimidazole (CDI) (81 mg, 1.5 mmol). The resulting solution was stirred for 8 hours at room temperature and the solvent was evaporated in vacuo to a residue. The residue was purified by chromatography (50% CH2Cl2-hexanes) to give 139 mg (63% yield) of the title compound: mp 240° C.; 1H NMR (400 MHz, CDCl3) δ1.65 (m, 1H), 2.01 (m, 1H), 2.70 (m, 2H), 3.55 (m, 1H), 3.63 (m, 1H), 4.05 (m, 1H), 4.68 (bs, 1H, OH), 6.41 (d, J=7.9, 1H), 6.60 (d, J=7.9, 1H), 10.36 (s, 1H), 10.37 (s, 1H); IR: 3250, 3080, 2980, 1700, 1500, 1210 cm−1; MS 220 [M]+.
