Procedure
A mixture of hydroxy[6-{[4-(trifluoromethoxy)phenyl]sulfonyl}-2-(trifluoromethyl)-6,11-dihydro-5H-pyrido[2,3-b][1,5]benzodiazepin-8-yl]acetic acid (51 mg, 0.091 mmol, Example 513), BOP (60.1 mg, 0.136 mmol), MeNH2—HCl (12.2 mg, 0.181 mmol), and diisopropylethylamine (0.08 ml, 0.453 mmol) in DMF was stirred for 2.5 h at rt. LC-MS showed the reaction complete. The solution was concentrated and the residue was purified by mass-directed HPLC eluting with H2O/MeCN/TFA (90:10:0.1-10:90:0.1) to give the title compound; Mass Spectrum: m/e=576 (M+1).
