Participants

Reaction Steps

The title compound (160.4 mg) was prepared as in Example 263 from 301 mg of the triflate from Step B and 185 mg of 4-fluorophenylboronic acid. The sequence also produced 2-cyclopentyl-3-(4-fluoro-phenyl)-5-methyl-2,4,5,6,7,8-hexahydro-1,2,6-triaza-azulene. The isomers were separated by SFC chromotagraphy.
