Reaction Steps

17-(cyclopropylmethyl)-4,5a-epoxy-3,14-dihydroxy-6-(1,3-dioxolan-2-yl)morphinan (3.85 g, 10 mmol) was dissolved in 10 ml of THF, then triethylamine (1.01 g, 10 mmol) and tert-butyldiphenyl chlorosilane (2.75 g, 10 mmol) were added with stirring. The whole system was reacted at a temperature ranging from 45° C. to 50° C. for 2 hours. After the reaction was complete, water was added to the system and the resultant mixture was extracted with diethyl ether for 3 times. The organic layer was washed with water, dried over anhydrous magnesium sulfate, and concentrated for crystallization to afford a white solid.
