1-(phenylmethoxymethyl)cyclopropane-1-sulfonyl chloride

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Using the same reaction conditions and workup as described for the preparation of Example 19A, 8-amino-7-(2-fluoro-4-iodo-phenylamino)-6-methyl-2,3-dihydro-thiazolo[3,2-a]pyridin-5-one (I-19f: 0.2 g, 0.048 mmol) in pyridine (2 mL) was reacted with 1-benzyloxymethyl-cyclopropanesulfonyl chloride (137 mg, 0.52 mmol) to afford the crude product. Purification by column chromatography on silica gel (50% ethylacetate in hexane) afforded 0.21 g of the product (70% yield). the same reaction conditions and workup to afford the crude product Purification by column chromatography on silica gel (50% ethylacetate in hexane)
