PREPARATIVE EXAMPLE 9; STEP B; (Bhattacharyya, S. Tetrahedron Lett. 1994,35, 2401.) [] A mixture of the title compound from Step A (1.09 g, 5.04 mmol, 1.0 eq.), paraformaldehyde (300 mg, ? 10.08 mmol, 2.0 eq.), and titanium isopropoxide (1.5 ml, 5.04 mmol, 1.0 eq.) in absolute ethanol (5 ml) was stirred at 70 C for 30 minutes and at room temperature for another 30 minutes. Sodium borohydride (195 mg, 5.04 mmol, 1.0 eq.) was added to the colorless solution. The solution was stirred at room temperature for 12h and at 60 C for another 3h. The solution was cooled to 0 C and treated with a 2.0M aqueous ammonia solution (25 ml, 50.00 mmol, excess) to give a snow-white suspension. The suspension was filtered through a Celite 521 plug and the filtrate was extracted with diethyl ether (4 x 25 ml). The ethereal extracts were combined and washed with brine (10 ml), dried over Na2SO4, filtered, and concentrated under house vacuum at 30 C. The residue was flash chromatographed (CH2Cl2 : 10% NH4OH/MeOH = 9:1 v/v) over silica gel to give the title compound (1.10 g, 95%) as a light-yellow, viscous oil. MS (EI): m/z 231 ([M+H]+, 59%), 175(B+). HR-MS(FAB):Calculated for C11H22N2O3 ([M+H]+): 231.1709. Found: 231.1716.
