Reaction Steps

To a solution of 6-fluoro-5-(1-methoxycarbonyl-2-methyl-2-propenyloxycarbonylamino)-3-propargyl-2(3H)-benzothiazolone (10 g) in toluene (100 g), sodium methylate was added in an amount of 0.05 equivalent to one equivalent of the benzothiazolone. The resulting mixture was refluxed for 3 hours, cooled to room temperature, combined with water and extracted with ethyl acetate. The organic layer was purified by silica gel column chromatography to give Compound No. 40 (6.8 g).
