Reaction Steps

tert-butyl 3-methyl-7-(1-methyl-1H-pyrazol-4-yl)-3,4-dihydroisoquinoline-2(1H)-carboxylate (0.320 g, 0.977 mmol) in ethyl acetate (1 mL) was treated with 4.0 M of hydrogen chloride in 1,4-dioxane (1.00 mL, 4.00 mmol) at r.t. for 1 h. The mixture was diluted with ether (5 mL), and was centrifugalized. The solvents were decanted. The residue was dried in-vacuo, and dissolved in tert-butanol (10 mL). To the solution was added 2-amino-4,6-dichloropyrimidine (0.246 g, 1.50 mmol) and N,N-diisopropylethylamine (522 uL, 3.00 mmol). The mixture was heated and stirred at 120° C. overnight. The solvent was removed under reduced pressure. The residue was purified by flash chromatography on a silica gel column with methanol in DCM (0-10%) to give the desired product (303 mg, 87.6%). LCMS (M+H)+: m/z=355.1/357.1.
