Participants

Reaction Steps

2.5 g (12.3 mmol) of the compound from Example 1A and 1.70 g (12.3 mmol) of potassium carbonate are placed in 30 ml dichloromethane and slowly treated at RT with a solution of 1.46 g (12.9 mmol) of chloroacetyl chloride in 5 ml dichloromethane. The mixture is stirred for 3 hrs at RT and then treated with 150 ml water and slowly with 30 ml 1 N hydrochloric acid. It is extracted three times with dichloromethane. The combined organic phases are dried over magnesium sulphate and freed of solvent on the rotary evaporator. 2.65 g (77% of theory) of the title compound are thus obtained.
