Reaction Steps

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 (100 mg, 0.45 mmol) in CH2Cl2/pyridine 9/1 (20 ml) was treated with 4-isopropylbenzenesulfonyl chloride (130 μl, 0.72 mmol). Purification by flash column chromatography (CH2Cl2:methanol, 97:3) gave the title compound (85 mg, 47% for steps 31.4 and this step) as a gum.
