Participants

Reaction Steps

A 36% aqueous formaldehyde solution (20.1 mg, 2.51 mmol), 0.029 ml (0.502 mmol) of acetic acid, and 53.2 mg (0.251 mmol) of triacetoxysodium borohydride were successively added to a solution of 15 mg (0.084 mmol) of the title compound produced in step (iv) of Reference Example 12 in methanol (0.7 ml), and the mixture was stirred at room temperature for 15 min. Thereafter, the reaction solution was purified by preparative thin layer chromatography (chloroform:methanol:28% aqueous ammonia=9:2:0.2) to give 15 mg (yield 93%) of the title compound.
