(4-chloro-3-fluorophenyl)methanamine

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: The title compound or its salt was prepared by a procedure similar to that described for E59 starting from (4-chloro-3-fluorophenyl)methanamine and 8-chloro-1-methyl-3,4-dihydro-1H-pyrimido[1,6-a]pyrimidin-6(2H)-one.

Conditions: temp:96.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of (2-methylpyridin-4-yl)boronic acid 15-1 (822 mg, 6.2 mmol), (4-chloro-3-fluorophenyl)methanamine 15-2 (798 mg, 5.00 mmol), Pd(PPh3)4 (173 mg, 0.15 mmol) and K3PO4 (1.59 g, 7.50 mmol) in dioxane (10 mL) and water (1 mL) was stirred at 96° C. under argon overnight. After cooling to room temperature, the mixture was filtered through celite, washed with ethyl acetate, and dried with Na2SO4. The filtrate was concentrated by rotavap and the residue subjected to silica gel column chromatography with 6% ammonia-saturated methanol in dichloromethane as eluent to give (3-fluoro-4-(2-methylpyridin-4-yl)phenyl)methanamine 15-3 as an oil. After cooling to room temperature the mixture was filtered through celite washed with ethyl acetate dried with Na2SO4 The filtrate was concentrated by rotavap
