2-Methylphenyl boronic acid → 4-(2-Methylphenyl)-6-[3,5-bis(trifluoromethyl)benzyl]-6,7,8,9-tetrahydro-5H-10-oxa-1,6-diazabenzocyclooctene-5-one

Participants

Reaction Steps

In a similar manner to Reference Example 5, 5-[3,5-bis(trifluoromethyl)benzyl]-7-iodo6-oxo-2,3,4,5-tetrahydro-6H-pyrido[2,3-b][1,5]oxazocine (compound of Reference Example 3; 300 mg) was reacted with 2-methylphenylboronic acid (116 mg) to obtain 5-[3,5-bis(trifluoromethyl)benzyl]-7-(2-methylphenyl)-6-oxo-2,3,4,5-tetrahydro-6H-pyrido[2,3-b][1,5]oxazocine (278 mg, 99%).
