Reaction Steps

Compound 1 was saponified with 1.0 ml sodium hydroxide solution (6N, water) in 20.0 ml ethanol. The ethanolic solution was concentrated to small volume on a rotary evaporator, the residue was taken up in water, reacted with 6N HCl and the aqueous solution extracted three times over ether. The organic phase was washed neutral with water, dried over magnesium sulphate and concentrated to a reduced volume on a rotary evaporator.
