Example 141 : N-tert-Butyl-2-(6-{5-chloro-2-[(oxan-4-yl)amino]pyrimidin-4-yl}-1 -oxo-2,3- dihydro-1 H-isoindol-2-yl)acetamide (2628) (2629) A stirred solution of 2-(6-{5-chloro-2-[(oxan-4-yl)amino]pyrimidin-4-yl}-1-oxo-2,3-dihydro-1 H- isoindol-2-yl)acetic acid (Example 1 , 60 mg, 0.10 mmol, 70 % pure) in anhydrous 1 ,4- dioxane/DMF (3 : 1 , 1.5 mL) under nitrogen was treated with DIPEA (36 muIota_, 0.21 mmol), HBTU (81 mg, 0.21 mmol) and then tert-butylamine (17 muIota_, 0.16 mmol). The reaction was stirred for 4 days at room temperature and quenched by adding water. The product was extracted with EtOAc (x3) and the combined organic layers washed with brine, dried over MgS04, filtered and concentrated under vacuum. Purification by preparative HPLC gave the title compound (32 mg, 70 %) as a colourless solid. NMR (400 MHz, Me-c/3-OD): 8.36 (1 H, s), 8.24 (1 H, d), 8.08 (1 H, dd), 7.71 (1 H, dd), 4.66 (2H, s), 4.28 (2H, s), 4.1 1-4.02 (1 H, m), 4.02-3.95 (2H, m), 3.59-3.51 (2H, m), 2.05-1.97 (2H, m), 1.69-1.58 (2H, m), 1.38 (9H, s). MS: [M+H]+ = 458.

With the complex challenges of chemical substances, we look forward to future research findings about 3-Methyl-1,2,3,4-tetrahydroisoquinoline,belong tetrahydroisoquinoline compound

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.29726-60-1,3-Methyl-1,2,3,4-tetrahydroisoquinoline,as a common compound, the synthetic route is as follows.,29726-60-1

To a mixture of pyrazole acid (1 mmol), EDC.HCl (1.2 mmol) and HOBt (1.2 mmol) in dry dichloromethane (10 mL) was added a mixture of amine (1 mmol) and triethyl amine (1.5 mmol) in dichloromethane (5 mL) at 0 C. The mixture was stirred at room temperature till the completion of reaction (judged by TLC). The reaction mixture was diluted with additional DCM (20 mL). The organic layer was washed with water, brine and dried (Na2SO4). Concentration and purification over silica gel (100-200 mesh) afforded the desired compound.
