Sodium Bicarbonate → HCID 25002937, compound

Participants

Reaction Steps

To a solution of intermediate 12 (2 mmol) in 1,4-dioxane (6 ml) and a saturated solution of NaHCO3 (6 ml) was added intermediate 6 (0.51 g, 2 mmol). The resulting solution was degassed using a stream of nitrogen and to this was added Pd(PPh3)4 (0.231 mg, 0.2 mmol). The reaction was then microwaved in a sealed tube at 150° C. for 10 minutes. The resulting cooled reaction mixture was filtered through a pad of diatomaceous earth and concentrated in vacuo. The crude reaction mixture was then purified by column chromatography (silica gel; DCM to DCM/MeOH up to 3% as eluent). The desired fractions were collected and evaporated in vacuo to yield compound 2 (0.405 g, 52%).
