Reaction Conditions:
with phosphorus tribromide in chloroform at 45;
Steps:
5.2.22 4-(Bromomethyl)pyridinium bromide (19) [27]
Compound 18 (1.810g, 16.58mmol) was dissolved in 48% HBr (16mL) and stirred at reflux for 4h. The water was removed in vacuo to give a thick gum which was treated with ethanol at 5°C and then filtered. The white crystals were collected and washed with cold ethanol to get 4-(hydroxymethyl)pyridinium bromide (1.9g). To a suspension of this salt in chloroform (25mL) PBr3 (457μL, 4.85mmol) was added, and the mixture was stirred at reflux for 4.5h. After cooling down to 25°C, the white precipitate was collected and washed with cold chloroform to give 19 (2.3g, 93%) as a white solid. 1H NMR (300MHz, CDCl3) δ 8.80 (d, J=6.4Hz, 2H), 8.00 (d, J=6.4Hz, 2H), 4.61 (s, 2H). The spectroscopic data are consistent with those reported in literature [27].
