2,2-dimethylpropanimidamide

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

Procedure: A mixture of methyl 3-cyclobutyl-3-oxo-propanoate (4.3 g, 27.53 mmol) and 2,2-dimethylpropanamidine (2.3 g, 22.10 mmol) was stirred in dry MeOH (50 mL) and NaOMe (5.0 g, 92 mmol) was added in portions at 10° C. The suspension was stirred at room temperature overnight. The reaction mixture was concentrated to roughly half of the volume and filtered. The filtrate was extracted with water and DCM. The combined organic layers were washed with brine, dried over Na2SO4, filtered, and concentrated under reduced pressure. The residue was stirred with acetone and the precipitate collected, dried under vacuum to give the title compound (3.15 g, 15.27 mmol, 66%). The reaction mixture was concentrated to roughly half of the volume filtered The filtrate was extracted with water and DCM The combined organic layers were washed with brine dried over Na2SO4 filtered concentrated under reduced pressure The residue was stirred with acetone the precipitate collected dried under vacuum

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

Procedure: A mixture of (5-(3-aminopyridin-2-yloxy)-3,4-dihydroquinolin-1(2H)-yl)(phenyl)methanone (Example A171d) (224 mg, 0.58 mmol), 1,1′-thiocarbonyldi-2(1H)-pyridone (269 mg, 1.16 mmol) in DCM (10 mL) was agitated at rt for 4 h. The mixture was evaporated and diluted in THF (5 mL), pivalamidine (79 mg, 0.58 mmol) and DIPEA (205 μL, 1.16 mmol) were added and mixture was heated at 80° C. in a sealed tube for 24 h. The solution was cooled down and DEAD (183 μL, 1.16 mmol) was added, mixture was stirred for 2 h. The reaction mixture was evaporated in vacuo and purified using preparative HPLC to afford the final product (40 mg). (M+H)+=486. The mixture was evaporated diluted in THF (5 mL) mixture was heated at 80° C. in a sealed tube for 24 h The solution was cooled down mixture was stirred for 2 h The reaction mixture was evaporated in vacuo purified
