Yield: 79.3% ， 11.3%

Reaction Conditions:

with C31H37ClN3NiO2(1-)*Li(1+) in tetrahydrofuran at 25; for 0.333333 h;Inert atmosphere;Overall yield = 90.4 %;

Steps:

2.4 Cross coupling of CH2Cl2 with butylmagnesium chloride
General procedure: Cross-coupling reactions of Grignard reagents with CH2Cl2 were performed according to the following general method. Catalyst 2 (1.0 mg, 1.74 μmol) in 1.0 mL THF was added using a gas-tight syringe to a 5 mL round bottom flask purged with N2. To this solution, 2 M n-butylmagnesium chloride in THF (0.42 mL, 0.84 mmol) was added. CH2Cl2 (27 μL, 0.42 mmol) in 2 mL THF was added to the reaction mixture. Samples were collected for analysis after 20 min. At the end of the reaction, excess Grignard reagent was destroyed using methanol and the reaction products were analyzed by GC-MS using an internal standard to quantify product formation.
