Reaction Steps
60% Sodium hydride (0.232 g) was gradually added to a tetrahydrofuran (4.5 ml) solution containing 1-tert-butoxycarbonyl-4-hydroxypiperidine (0.900 g) and 2-chloropyrimidine (0.666 g), and 2 hours later, dimethyl sulfoxide (1.0 ml) was added thereto, and the mixture was stirred at room temperature for 1 day to undergo reaction, thereby obtaining 1-tert-butoxycarbonyl-4-(2-pyrimidinyloxy)piperidine. This compound was acid-treated with hydrochloric acid to obtain 4-(2-pyrimidinyloxy)piperidine.hydrochloride.
