실험 절차

300 mg (1.13 mmol) 6-(Piperidine-4-yloxy)-isoquinoline hydrochloride (124) are dissolved in 10 mL of methanol. 202 mg of triethylamine, molecular sieves 4A, 600 mg of glacial acetic acid, 871 mg of (1-Ethoxy-cyclopropyloxy)-trimethyl-silane and 101 mg of sodium cyanoborohydride are added successively and the reaction mixture is heated under reflux for 6 hours. The reaction mixture is cooled to room temperature, 6 mL of 2N sodium hydroxide are added and the reaction mixture is filtered. The filtrate is evaporated, the residue is taken up in dichloromethane, extracted with 2 N sodium hydroxide and brine, dried with sodium sulfate, evaporated to dryness and the crude material is purified by preparative HPLC. The product fractions are evaporated, the product is taken up in 2 N hydrochloric acid and lyophilized.
