The reaction mixture was stirred at RT for 0.5 h. Then (R)-1-(4-fluoronaphthalen-1-yl)ethanamine (0.832 g, 4.40 mmol) was added and the reaction mixture was stirred at RT for 2 h. After completion of reaction ice was added to reaction mixture, solid precipitated out was filtered through Buchner funnel to get title compound (830 mg, 58.1%); m/z 390.54. Crude was taken without purification for next reaction.
