Participants

Reaction Steps

1 ml of AcOH and 0.129 g of dimethylamine hydrochloride are added to a solution of 0.830 g of the compound obtained in step A of Example 17 in 10 ml of DCM, followed by portionwise addition of 0.456 g of sodium triacetoxyborohydride, and the mixture is stirred for 18 hours at RT. The reaction mixture is diluted with DCM, the organic phase is washed with saturated NaCl solution and dried over Na2SO4, and the solvent is evaporated off under vacuum. The residue is chromatographed on silica gel, eluting with a chloroform/MeOH mixture (95/5; v/v). 0.52 g of the expected product is obtained.
