Procedure

2-Amino-4-(benzo[1,3]dioxole-5-carbonyl)-thieno[2,3-d]pyrimidine-6-carboxylic acid ethyl ester (example 312) (100 mg) was dissolved in anhydrous THF under a nitrogen atmosphere before methyl magnesium bromide (3.0M solution in diethyl ether, 5 equiv.) was added. The solution was stirred at 40° C. overnight before being partitioned between 10% aqueous ammonium chloride solution and ethyl acetate. The organic layer was washed with brine, dried over magnesium sulphate and evaporated to yield a crude product that was purified by preparative TLC to give the desired compound as a yellow powder.
