実験手順

To a solution of N-(2,6-diethylphenyl)-1-methyl-8-(piperidin-4-ylamino)-4,5-dihydro-1H-pyrazolo[4,3-h]quinazoline-3-carboxamide hydrochloride (300 mg, 0.606 mmol) under nitrogen, in dry dichloromethane (15 mL), DIPEA (0.527 mL, 3.03 mmol) and 300 mg of molecular sieves were added, and the mixture was cooled at −78° C. 2-chloroethanesulfonyl chloride (0.063 mL, 0.606 mmol) was added. Temperature was allow to rise to room temperature then the solvent was evaporated to dryness and the crude was purified by flash chromatography on silica gel (eluant: ethyl acetate/dichloromethane: 2/8) to give 185 mg of the title compound (56% yield).
