5.50g (0.02 mol) of p-phenylphenacyl bromide were dissolved in 56 cc of
anhydrous acetone previously heated to about 40°C. This solution was added,
with stirring, to a solution of 5.70 g (0.02 mol) of 1-hyoscyamine in 43 cc of
anhydrous acetone; the reaction solution was maintained at 45°C and stirred
for about six hours.
After standing overnight in the refrigerator, the precipitate was collected by
filtration and dried in vacuo at 60°C. Yield: 10.2 g; MP = 193°C to 194°C.
