Example 24. Preparation of 5-chloro-3-isopropyl-N-methyl-N-(tetrahydro-2H-pyran-4-yl) pyrazolo[ 1 ,5-a]pyrimidin-7-amine [00201] Step 1: Synthesis of 5-chloro-3-isopropyl-N-methyl-N-(tetrahydro-2H-pyran- 4-yl) pyrazolo[l,5-a]pyrimidin-7-amine. A mixture of 5,7-dichloro-3- isopropylpyrazolo[l,5-a]pyrimidine (687 mg, 3.0 mmol), N-methyl-tetrahydro-2H-pyran-4- amine (414 mg, 3.6 mmol), and K2C03 (828 mg, 6.0 mmol) in 10 mL of acetonitrile was heated at reflux under N2 for 2 h., diluted with water (10 mL) and the mixture was extracted with EtOAc (15 mL X 3). The combined organic phases were dried over Na2S04, filtered and concentrated. The residue was purified by preparative TLC on silica gel (petroleum ether/EtOAc = 3/1) to afford 5-chloro-3-isopropyl- N-methyl-N-(tetrahydro-2H-pyran-4- yl)pyrazolo[l,5-a] pyrimidin-7- amine (813 mg, 88 % yield) as yellow solid. ESI-LCMS (m z): 309.1 [M+l]+., 220641-87-2

Example 10; 1-[(E)-3-(3,4-Dichloro-phenyl)-acryloyl]-4-{4-[methyl-(tetrahydro-pyran-4-yl)-amino]-butyl}-[1,4]diazepan-5-one; 1-[(E)-3-(3,4-Dichloro-phenyl)-acryloyl]-4-{4-[methyl-(tetrahydro-pyran-4-yl)-amino]-butyl}-[1,4]diazepan-5-one; A solution of 0.100 g (0.20 mmol) of 1-[(E)-3-(3,4-dichloro-phenyl)-acryloyl]-4-(4-iodo-butyl)-[1,4]diazepan-5-one (example 9B) in 3.1 ml of DMA was treated with free methyl-(tetrahydro-pyran-4-yl)-amine in 1 ml of toluene [0.035 g (0.22 mmol) methyl-(tetrahydro-pyran-4-yl)-amine hydrochloride were dissolved in 0.8 ml of 0.5 N NaOH was extracted with toluene (2 ml). The organic phase was dried over Na2SO4] and stirred for 22 h at RT, 0.06 ml (0.40 mmol) of Et3N was added and stirring was continued for 18 h at 50 C. Again methyl-(tetrahydro-pyran-4-yl)-amine in 1 ml of CH2Cl2 [0.035 g (0.22 mmol) methyl-(tetrahydro-pyran-4-yl)-amine hydrochloridewere dissolved in 0.5 ml aqueous 10% NaCl solution/0.4 ml of 1 N NaOH was extracted with CH2Cl2 (1 ml). The organic phase was dried over Na2SO4] was added and heated for 9 h at 50 C. The reaction was extracted with aqueous saturated NaHCO3/Et2O (3¡Á). The organic phases were washed with aqueous 10% NaCl, dried (Na2SO4), concentrated and evaporated. Purification by catridges, Si-Amine, 70 ml, 20 g (n-heptane/EtOAc 1:4 to 1:9) gave 0.004 g (4%) of the title compound as a light yellow semisolid. MS: 482.3 (MH+, 2Cl).
