Reaction Steps

1 eq. of the compound obtained in Step G is dissolved in 4 ml of pyridine and is cooled in an ice bath before adding 3 eq. of acetic anhydride dropwise. The reaction mixture is stirred for 5 hours at ambient temperature and is then poured into 3M HCl solution and extracted with ethyl ether. The organic phase is washed with 10% potassium carbonate solution and then with water, dried over MgSO4 and evaporated under reduced pressure. The oil obtained is precipitated from a mixture of ethyl ether/petroleum ether (1/2) and the precipitate formed is filtered off under suction and recrystallised.
