Procedure

(5-Methyl-1H-pyrazol-3-yl)[6-{[4-(trifluoromethoxy)phenyl]sulfonyl}-2-(trifluoromethyl)-6,11-dihydro-5H-pyrido[2,3-b][1,5]benzodiazepin-8-yl]methanone To a solution of 8-iodo-6-{[4-(trifluoromethoxy)phenyl]sulfonyl}-2-(trifluoromethyl)-6,11-dihydro-5H-pyrido[2,3-b][1,5]benzodiazepine (950 mg, 1.544 mmol, intermediate 61) in 5 ml of THF was added a solution of isopropyl magnesium chloride (3.47 ml, 6.95 mmol) in THF (2M) at 0° C. The solution was stirred at 0° C. for 30 min, then a mixture of N-methoxy-N,5-dimethyl-1H-pyrazole-3-carboxamide (261 mg, 1.544 mmol) in 3 mL of toluene was added. The reaction mixture was stirred for 2 hr at 0° C. and then allowed to warm to rt overnight. The reaction was quenched by the addition of 4 mL of 0.5 N HCl. The resulting viscous residue was washed with ethyl acetate (30 mL×2) and acetone (20 mL×2). The combined washes were evaporated under reduced pressure and the residue was crystallized from CH2Cl2 to give the title compound as a light yellow solid; Mass Spectrum: m/e=598 (M+1).
