PROCEDURE

实验过程

Following the same procedure as described in example 31.5, a portion of crude N-(7-amino-3,4-dihydro-2H-pyrano[3,2-b]pyridin-3-yl)-propionamide (95 mg, 0.43 mmol) in CH2Cl2/pyridine 9/1 (10 ml) was treated with 4-((S)-2-fluoro-1-methyl-ethyl)benzenesulfonyl chloride (132 mg, 0.55 mmol). Purification by flash column chromatography (CH2Cl2:MeOH, 97:3) gave the title compound (100 mg, 55% for step 31.4 and this step) as a gum.
