Reaction Conditions

Reaction Steps

150 mg (0.57 mmol) of the compound of Example 24A were dissolved in 1.5 ml of methanol, 0.25 ml (1.14 mmol) of a 25% strength solution of sodium methoxide in methanol and 0.04 ml (0.62 mmol) of methyl iodide were added and the mixture was heated in a microwave oven (Biotage Initiator, with Dynamic Field Tuning) at 120° C. for 30 min. After cooling, the reaction was acidified with 1 M hydrochloric acid and concentrated slightly on a rotary evaporator. The precipitate formed was filtered off, washed with water and dried under high vacuum. This gave 96 mg (94% pure, 57% of theory) of the title compound.
