Reaction Steps
Using essentially the same procedure as Example 5-22, Step 4, Pd(OAc)2 (7.04 mg, 0.03 mmol), X-Phos (29.9 mg, 0.06 mmol), potassium carbonate (434 mg, 3.14 mmol), potassium cyclopropyltrifluoroborate (170 mg, 1.15 mmol) and 6-chloro-2,2-dimethyl-3,4-dihydro-2H-chromene-8-carbaldehyde (235 mg, 1.05 mmol, Example 5-26, Step 3) afforded the desired product as a pale-yellow oil.
