YieldReaction ConditionsOperation in experiment
Example 38; 3-Chloro-N-(2-cyclobutyl-pyrimidin-4-yl)-2-methyl-benzenesulfonamide; Step A]: 2-Cyclobutyl-pyrimidin-4-ylamine; This intermediate was made according to example 2, step A] method from cyclobutanecarboxamidine hydrochloride (0.3 g, obtained from <strong>[4426-11-3]cyclobutanecarbonitrile</strong> in analogy to Synth. Commun. 12 (13), 1982, 989-993 and Tetrahedron Lett. 31 (14), 1990, 1969-1972) and 3-ethoxy-acrylonitrile (0.3 g). 2-Cyclobutyl-pyrimidin-4-ylamine was obtained as a light brown solid (0.26 g): 1H NMR (delta, DMSO-d6): 7.98 (d, 1H), 6.66 (br s, 2H), 6.21 (s, 1H), 3.35-3-37 (m, 1H), 2.33-2.23 (m, 2H), 2.19-2.12 (m, 2H), 1.99-1.88 (m, 1H), 1.82-1.74 (m, 1H).
Step 2: Cyclobutanecarboximidamide hydrochloride Hydrogen chloride gas was bubbled through a solution of <strong>[4426-11-3]cyclobutanecarbonitrile</strong> (2.0 g, 24.65 mmol) in methanol (10 mL) and diethyl ether (12 mL) for 2 h at 0C. The reaction mixture was concentrated under reduced pressure and the residue was dissolved in methanol and cooled to 0C. Methanolic ammonia was added and the reaction mixture was stirred for 1 h at room temperature. The solvent was removed under reduced pressure to afford cyclobutanecarboximidamide hydrochloride (3.0 g, 92%). The material was used for the next step without further purification.
