The synthetic route is as follows., Application In Synthesis of 3-(tert-Butyl)-1-(p-tolyl)-1H-pyrazol-5-amine
N- (5-TERT-BUTVL-2-P-TOLVL-2H-PVRAZOL-3-VL)-2-F 4-F2-MORPHOLIN-4-VL-ETHOXV- naphthalen-1-yl]-2-oxo-acetamide, (13); Compound 12 (0. 224 g, 0. 653 mmol) was dissolved in THF (20 mL). To this solution was added 1 N LIOH (3 eq, 1. 96 mmol). The solution was allowed to stir for 2 hours then neutralized with 4 N HCl in dioxane and the solvent was evaporated providing a white solid. The residue was dried under high vacuum at 80C for 30 minutes and then suspended in CH2C12 (50 mL). To the suspension was added oxalyl chloride (0. 56 mL, 6. 53 mmol) and few drops of DMF. The suspension was stirred at room temperature for 2 hrs then the solvent evaporated. The resulting solid was suspended in ethyl acetate (20 mL) and added to 5-AMINO-3-T-BUTYL-L- (4-METHYLPHENYL) pyrazole (1) (0. 159 g, 0. 663 mmol) dissolved in ethyl acetate (20 mL) and a 50% NAHC03 solution (10 mL) and stirred overnight at 60C. The mixture was diluted with ethyl acetate and extracted with NaHCO3. The combined organic layers were washed with brine, dried over MGS04, filtered and the solvent removed leaving a brown oil. The material was purified by column chromatography (50-100% EtOAc/Hexanes) or (0-5% methanol/DCM) providing 0. 346 g (98%) of the desired compound as a yellow solid. LC-MS : Calculated mass= 540. Observed mass= 541.
