YieldReaction ConditionsOperation in experiment
93% With N-ethyl-N,N-diisopropylamine; In dichloromethane; at -78℃; for 2.25h;Inert atmosphere; PREPARATION 2 2-Chloro-9-(tetrahydro-2H-pyran-4-yl)-7,9-dihydro-8H-purin-8-one [Show Image]a) 2-Chloro-5-nitro-N-(tetrahydro-2H-pyran-4-yl)pyrimidin-4-amine Diisopropylethylamine (19.80 mL, 110 mmol) was added dropwise over 15 minutes to a stirred suspension of 2,4-dichloro-5-nitropyrimidine (11.56 g, 60 mmol) and <strong>[33024-60-1]tetrahydro-2H-pyran-4-amine hydrochloride</strong> (WO200424728 A2) (7.81 g, 60 mmol) in dichloromethane (400 mL) at -78 °C under a nitrogen atmosphere. The reaction mixture was stirred at -78 °C for 2 hours and then was allowed to warm to ambient temperature. The solvent was evaporated, water was added and the resultant solid was filtered, washed with water and dried to yield the title compound (13.62 g, 93percent) as a yellow solid. LRMS (m/z): 259 (M+1)+.1H NMR (300 MHz, CDCl3) delta ppm 1.62 - 1.80 (m, 2H), 2.06 (d, 2H), 3.59 (t, 2H), 4.04 (d, 2H), 4.45 (td, 1H), 8.33 (br s, 1H), 9.07 (s, 1H).
