Reaction Steps

To a solution of 112f (2.0 g, 7.5 mmol) in MeCN (60 ml) was added HCHO (1.4 ml, 16 mmol) and 5 drops of AcOH at room temperature. Then NaCNBH3 (1 g, 16 mmol) added and the mixture was stirred for 2 h. It was poured onto water and extracted with EA (100*3). The organic layer was dried over Na2SO4, filtered off, evaporated, and purified through a silica gel column eluting with PE:EA=5:1 to 1:1 to give 112g as a colorless oil (1.5 g, 72%) MS: [M+H]+: 283
