Procedure

Sodium borohydride (1.135 g, 30 mmol) is added to a solution of aldehyde 138 (6.849 g, 30 mmol) in 100 ml of methanol cooled to 0° C. The resulting solution is stirred at 0° C. for 30 min, evaporated and the residue dissolved in 150 ml of ethyl acetate, washed with water and brine, dried over Na2SO4, concentrated and taken to dryness under high vacuum to give the product 139 as an oil. MS (+VE) m/z 231 (M+1).
