Procedure

To a stirred solution of N-(1-adamantylmethyl)-5-chloro-2-(3-hydroxypropyl)isonicotinamide (0.12 g, 0.33 mmol) (Example 14(ii)) in dry dichloromethane (10 mL) Dess-Martin periodinane (0.14 g, 0.33 mmol) was added. The resulting mixture was stirred at room temperature for 4 hours. The reaction was treated with diethyl ether (20 mL) and a saturated sodium bicarbonate solution containing sodium thiosulfate (0.37 g, in 4 mL). The mixture was stirred for 10 minutes and the organics separated; washed with brine (10 mL); dried over anhydrous magnesium sulfate; filtered; treated with acetic acid (0.30 mL) and concentrated. MS: APCI(+ve) 361, 363 (M+1).
